PtS2/GeC van der Waals heterostructure: a promising direct Z-scheme photocatalyst with high solar-to-hydrogen energy conversion efficiency for overall water splitting under acidic, alkaline, and neutral conditions and in large-strain regions

In this study, first-principles calculations were used to investigate in detail the structural, electronic, optical, and photocatalytic properties of PtS 2 /GeC heterostructures.
