	Integrated environmental remediation is increasingly focused on the development of multifunctional materials capable of simultaneous detection of toxic gases and wastewater treatment. Present study aims to develop dual-functional LaFeO3 perovskites for gas sensing and photocatalytic dye degradation. The nanocrystalline powders of LaFeO3 were synthesized via two distinct methods; auto-combustion (A-LFO) and hydrothermal (H-LFO). Numerous characterization techniques (e.g. XRD, SEM, EDAX, BET, TEM, and XPS) were utilized in order to study the phase, morphology, surface area and elemental composition of A-LFO and H-LFO samples. Both samples were systematically evaluated for their potential in the gas sensing and photocatalytic degradation of malachite green (MG). In results, A-LFO exhibited superior performance in both applications, compared to the H-LFO. It shows similar to 90 \% sensitivity for the acetone (500 ppm) at the operating temperature of 275 degrees C and achieved similar to 78 \% degradation efficiency for malachite green (MG) dye (5 ppm) within 2 h irradiation of natural sunlight. Although, H-LFO presented comparatively lower performance, both materials demonstrated good selectivity, and stability highlighting their promise as a dual-functional environmental remediation agent. By exploring the performance of the synthesized materials in these dual applications, this research established a relationship between synthesis methods, material properties, and overall performance in environmental and industrial applications, by offering a sustainable and efficient solution to complex pollution challenges.</p>
