Recent Progress, Challenges, and Prospects in Two-Dimensional Photo-Catalyst Materials and Environmental Remediation

The successful photo-catalyst library gives significant infor-mation on feature that a ects photo-catalytic performance and proposes new materials. Competency is considerably significant to form multi-functional photo-catalysts with flexible characteristics. Since recently, two-dimensional materials(2 DMs) gained much attention from researchers, due to their unique thickness-dependent uses, mainly for photo-catalytic, outstanding chemical and physical properties. Photo-catalytic water splitting and hydrogen(H) evolu-tion by plentiful compounds as electron(e~-) donors is estimated to participate in constructing clean method for solar H-formation. Heterogeneous photo-catalysis received much research attention caused by their applications to tackle numerous energy and environmental issues. This broad review explains pro-gress regarding 2 DMs, significance in structure, and catalytic results. We will discuss in detail current progresses of approaches for adjusting 2 DMs-based photo-catalysts to assess their photo-activity including doping, hetero-structure scheme, and functional formation assembly. Suggested plans, e.g., doping and sensitization of semiconducting 2 DMs, increasing electrical conductance, improving catalytic active sites, strengthening interface coupling in semiconductors(SCs) 2 DMs, forming nano-structures, building multi-junction nano-composites, increasing photo-stability of SCs, and using combined results of adapted approaches, are summed up. Hence, to further improve 2 DMs photo-catalyst properties, hetero-structure design-based 2 DMs’ photo-catalyst basic mechanism is also reviewed.
