	Gas-solid interactions between molecular oxygen and metallic vanadium surfaces and the systematic evolution in the electronic structure of vanadium oxide (VOx) surfaces have been explored in the present work by near-ambient pressure photo-electron spectroscopy (NAPPES). The current article studies the evolution of various oxides of vanadium as a function of partial pressure of O2 (ultrahigh vacuum to 1 mbar), temperature (298- 875 K), and the exposure time to oxygen (up to 18 h). Valence -band (VB) and core-level spectral measurements recorded with UV (He-I = 21.2 eV) and Al K alpha (1486.6 eV) photons, respectively, show interesting changes. (1) Oxidation is limited to the top layers of vanadium at 298 K and up to a partial pressure of 1 mbar O2. About 50% of vanadium gets oxidized, and the remaining amount exists as metal within the top 10 nm. (2) Metallic vanadium disappears above 625 K, and it is predominantly oxidized to a mixture of V4+ and V5+ oxidation states at a 0.1 mbar partial pressure of O2. Points 1 and 2 suggest the predominantly thermodynamically controlled nature of vanadium oxidation through oxygen diffusion into the subsurface and bulk layers. (3) The Fermi-level (EF) feature observed first at &amp;gt;= 725 K at a 0.1 mbar O2 pressure demonstrates the formation of metallic VO2; however, its metallic nature is preserved even at ambient temperature due to interweaving nanodomains of VOx with VO2. (4) Only partial conversion of surface layers to V5+ (V2O5) along with VO2 and V2O3 (within the probing depth of 8-10 nm by near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS)) was observed even after prolonged heating (18 h) in 1 mbar O2 pressure. (5) The nature of the surface changes between metal and semiconducting/ insulator oxides is substantiated by the observation of changes in work function (phi) and EF features. Typical VB features and Fermi intensity of V-metal and vanadium oxides were observed, and the results were corroborated with core-level and VB spectra. The present results extend the capabilities of NAPPES to explore the electronic structure evolution as a function of reaction conditions and underscore its relevance to areas such as heterogeneous catalysis and sensing.&lt;/p&gt;

	&lt;span style=&quot;color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif; font-size: 16px;&quot;&gt;In the landscape of green hydrogen production, alkaline water electrolysis is a well-established, yet not-so-cost-effective, technique due to the high overpotential requirement for the oxygen evolution reaction (OER). A low-voltage approach is proposed to overcome not only the OER challenge by favorably oxidizing abundant feedstock molecules with an earth-abundant catalyst but also to reduce the energy input required for hydrogen production. This alternative process not only generates carbon-negative green H&lt;/span&gt;&lt;span style=&quot;box-sizing: border-box; outline: none; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em; color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif;&quot;&gt;2&lt;/span&gt;&lt;span style=&quot;color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif; font-size: 16px;&quot;&gt;&amp;nbsp;but also yields concurrent value-added products (VAPs), thereby maximizing economic advantages and transforming waste into valuable resources. The essence of this study lies in a novel electrocatalyst material. In the present study, unique and two-dimensional (2D) ultrathin nanosheet phosphates featuring first-row transition metals are synthesized by a one-step solvothermal method, and evaluated for the electrocatalytic glycerol oxidation reaction (GLYOR) in an alkaline medium and simultaneous H&lt;/span&gt;&lt;span style=&quot;box-sizing: border-box; outline: none; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em; color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif;&quot;&gt;2&lt;/span&gt;&lt;span style=&quot;color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif; font-size: 16px;&quot;&gt;&amp;nbsp;production.

The 2D nanosheet morphology provides a large surface area and a high density of active sites. As a GLYOR catalyst, CoP ultrathin (∼5 nm) nanosheets exhibit remarkably low onset potential at 1.12 V (vs RHE), outperforming that of NiP, FeP, and CuP around 1.25 V (vs RHE). CoP displays 82% selective formate production, indicating a superior capacity for C–C cleavage and concurrent oxidation; this property could be utilized to valorize larger molecules. CoP also exhibits highly sustainable electrochemical stability for a continuous 200 h GLYOR operation, yielding 6.5 L of H&lt;/span&gt;&lt;span style=&quot;box-sizing: border-box; outline: none; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em; color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif;&quot;&gt;2&lt;/span&gt;&lt;span style=&quot;color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif; font-size: 16px;&quot;&gt;&amp;nbsp;production with a 4 cm&lt;/span&gt;&lt;span style=&quot;box-sizing: border-box; outline: none; line-height: 0; position: relative; vertical-align: baseline; top: -0.5em; color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif;&quot;&gt;2&lt;/span&gt;&lt;span style=&quot;color: rgb(21, 21, 21); font-family: Roboto, arial, sans-serif; font-size: 16px;&quot;&gt;&amp;nbsp;electrode and 98 ± 0.5% Faradaic efficiency. The present study advances our understanding of efficient GLYOR catalysts and underscores the potential of sustainable and economically viable green hydrogen production methodologies.&lt;/span&gt;&lt;/p&gt;
