CdS nanocages@defective-CoNi-LDH with bilayer porous hollow frameworks toward optimized sono-photocatalytic performance

“…Within the first 15 min of light exposure, HCNs@HD-CoNi-LDH showed the best photocatalytic degradation performance, which was attributed to the irregular structure of the HD-CoNi-LDH surface and the double-layer hollow framework; this provided more sites for adsorption, and this unique layered structure also promoted interfacial separation and transfer of photogenerated electrons and holes. 20,38,39 Additionally, HCNs@HD-CoNi-LDH exhibited 98% removal efficiency within 120 min, which was the highest efficiency among all samples. Similarly, HCNs@bulk-CoNi-LDH and SCNs@HD-CoNi-LDH samples were compared (Fig.…”

Surface Modification of 2D Photocatalysts for Solar Energy Conversion

“…[36,37] Generally, g-C 3 N 4 can be formed from various carbon-and nitrogen-rich precursors via simple high-temperature polymerization, and the corresponding reaction temperatures of different precursors are also varied (Figure 2B). [38][39][40][41][42][43] The first application of C 3 N 4 as photocatalytic materials can be traced back to 2009, in which Wang et al have developed g-C 3 N 4 in bulk phase as the catalyst for photocatalytic water splitting with relative good performance. [44] By manipulating the structure or composition, the energy band structure of g-C 3 N 4 can be easily adjusted, which makes it suitable for most photocatalytic processes.…”

Construction of a highly stable g-C3N4/NH2-MIL-88B(Fe)/CD@graphene oxide self-cleaning membrane for dye wastewater separation and degradation

“…At present, some research studies have been performed to improve the photocatalytic performance of g-C 3 N 4 by doping elements, constructing heterojunctions 14 and introducing co-catalysts. 15 Metal-organic frameworks (MOFs) are a kind of mixed porous material which is composed of a metal-oxygen cluster and an organic structure. Due to their large specific surface area, adjustable pore size, good stability, and excellent topological structure they are widely used in gas storage and separation, 16 sensing 17 and catalysis.…”
