Hydrogen Generation by Solar Water Splitting Using 2D Nanomaterials

Hydrogen is clearly the most environment-friendly alternative energy source available to us. The best way to produce hydrogen is to make use of the abundantly available solar power. This process is most beneficial both from energy and environmental aspects. A considerable effort is made to generate hydrogen by splitting water using a variety of inorganic catalysts, of which 2D materials are notable. Herein, a brief review of photocatalytic water splitting carried out using a variety of 2D catalysts is presented, including transition metal dichalcogenides, carbon nitride, heterostructures, and covalently cross-linked 2D composites.
