“…Since the first successful fabrication of graphene monolayers by Novoselov and Geim in 2004, 1 research has blossomed around two-dimensional (2D) materials, such as MoS 2 2 and Group III-N materials including BN, 3,4 GaN, 5 and AlN. 6,7 Demonstrating unique photoelectric performance, 8 these semiconductors have found utility in numerous applications, from electronic devices, 9,10 optical detectors, 11,12 and photocatalysts. 13–16 Recently, focus has shifted to harnessing 2D materials in designing effective photocatalysts to split water into hydrogen and oxygen, addressing environmental pollution and the energy crisis.…”
