Robust Photocatalytic Hydrogen Fuel Production via Water Splitting Using MXene-based Titanate Perovskite Composites

Abstract

A potential solution to the world's energy crisis may lie in this study's proposed method of producing hydrogen using photocatalytic water splitting, which is inexpensive, environmentally benign, and has a long half-life. We describe the process of developing and fabricating a strontium titanate (SrTiO₃) perovskite-based ternary photocatalyst with excellent performance. The bandgap can be fine-tuned by cautiously adding a co-catalyst, which substantially enhances the capacity to absorb visible light. The composite's ability to separate and transport charge carriers is greatly improved upon by the addition of MXene components.
