Dual-Function Photocatalytic Systems for Coupled Hydrogen Evolution and Pollutant Control

Abstract

Photocatalysis And Solar Fuels is advancing through efforts to align performance with evidence quality, resource limits, and transfer across settings. This article critically maps how dopant chemistry and redox cycling can unite solar-fuel production with contaminant treatment. The evidence base combines 2 focal papers with 12 independently retrieved publications verified through persistent DOI or publisher records. The analysis is organized around charge separation, active-site chemistry, reaction selectivity, materials stability, and reactor integration. Rather than treating results from heterogeneous studies as exchangeable, the review compares problem formulation, design assumptions, and transfer boundary. Across the literature, the literature consistently implies that advances in photocatalysis and solar fuels become credible when structure-property relationships are evaluated together and when uncertainty about operando characterization is reported explicitly. The comparative structure connects method selection to use-case risk and reveals common limits on generalization, and proposes a research agenda centered on transparent baselines, stress testing, and reproducible evidence.
