The design of efficient and stable visible-light-driven photocatalysts is paramount for sustainable hydrogen (H2) evolution the degradation organophosphorus pesticides, exemplified by dichlorvos (DDVP). In this work, we synthesized a co-catalyst-free nanocomposite photocatalyst composed Al6Si2O13 (ASO) Cd8.05Zn1.95S10 (ZCS). By constructing Type-I heterojunction, optimized ASO/ZCS-1 (ASO loading ratio: 30%) enhanced H2 activity (5.1 mmol g−1 h−1), nearly doubling that pristine ZCS (2.7 h−1). Stability assessments revealed catalytic durability over five successive cycles, whereas pure precipitously declined to 59.7% its initial level. Additionally, ASO, ZCS, ASO/ZCS-2 50%) demonstrated notable photocatalytic efficiency toward DDVP without any co-catalyst, reducing concentration 56.2% (ASO), 18.9% (ASO/ZCS-2), 38.4% (ZCS), with corresponding stability 93.8%, 95.1%, respectively. These results underscore superior ASO/ZCS in remediation heterojunction structure enhancing both stability. Comprehensive characterizations X-ray photoelectron spectroscopy (XPS), ultraviolet–visible diffuse reflectance (UV–vis DRS), differential charge density analyses verified charge-transfer mechanism, effectively suppressing recombination thus improving performance. Consequently, nanocomposites exhibit significant promise broad applications production, pollutant degradation, ensuring food agricultural product safety.
