The role of facet engineered surface and interface in CdS nanostructures toward solar driven hydrogen evolution

Review of Recent Developments in the Fabrication of ZnO/CdS Heterostructure Photocatalysts for Degradation of Organic Pollutants and Hydrogen Production

“…In the photocatalysis process, semiconductor materials have been extensively considered for the degradation of pollutants from wastewater, and the splitting of hydrogen and oxygen from water for clean fuel. TiO 2 , ZnO, SnO 2 , BiVO 4 , InVO 4 , WO 3 , Fe 2 O 3 , CdS, ZnS, and SnS are the various semiconductor materials which can be employed as an effective catalyst in photocatalysis [24][25][26][27][28][29][30][31][32][33]. However, recent reports have revealed that the photocatalytic activity of these individual semiconductors was limited for practical applications.…”

Crystal phase of nickel sulfide dictates hydrogen evolution activity of various semiconducting photocatalysts

“…The most widely used method to overcome this issue is depositing Pt cocatalyst onto a semiconducting photocatalyst surface. 22,23 Consequently, both the activity and stability can be improved because Pt with a large work function and zero-approaching hydrogen adsorption Gibbs free energy can greatly improve the charge separation, lower the H 2 formation energy barrier and avoid photo-corrosion. [24][25][26] However, the high price makes it unsuitable for large-scale applications.…”

Construction of MoS2/CdS heterojunction catalysts with crystal plane modulation for photocatalytic coupling of benzylamines under aerobic and anaerobic conditions

“…The {100} facets are more favorable for proton adsorption, which leads to higher photocatalytic performance of CdS nanorods mainly exposing the {100} facets as reactive sites during the hydrogen evolution process. 27 Zhang et al prepared CdS using the urothermal method, resulting in the formation of CdS with co-exposed {0001} and {101 ¯1} crystal planes. This unique crystal structure enables the formation of a type II heterojunction between the {0001} and {101 ¯1} crystal faces, leading to an enhanced photocatalytic hydrogen production activity.…”
