Synthesis of 2D/2D structural Ti3C2 MXene/g-C3N4 via the Schottky junction with metal oxides: Photocatalytic CO2 reduction with a cationic scavenger

Bi3O4Cl/g-C3N4/Cd0.5Zn0.5S Double Z-Scheme Heterojunction Photocatalyst for Highly Selective CO2 Reduction to Methane

“…It turns out that no CO 2 reduction products are detected in the photocatalyst system, revealing that these conditions are indispensable for CO 2 photoconversion. To ascertain the carbon sources of the obtained CO and CH 4 , an isotope labeling test was conducted using 13 CO 2 as feedstock. The characteristic peaks at m/z = 17, 29, and 45 are attributed to 13 CH 4 , 13 CO, and 13 CO 2 , respectively, indicating that CO 2 is the only carbon source (Figure S2a).…”

“…Hence, the electrons and holes with high power are accumulated separately and thus can provide a sufficient driving force for photocatalytic oxidation and reduction reactions. In the past decades, many CN-based binary Z-scheme heterojunctions such as BiVO 4 /g-C 3 N 4 , In 2 S 3 /g-C 3 N 4 , and Ti 3 C 2 MXene/g-C 3 N 4 have been developed and displayed excellent CRR performance. − The well-structured double Z-scheme photocatalyst has recently attracted wide attention for its further optimized separation of space charges driven by double interfaces and enhanced light absorption capacity. − However, as far as we know, CN-based double Z-scheme photocatalysts for CO 2 reduction have not been reported yet on account of the exploration of a ternary heterojunction with proper band structure alignment for a double Z-scheme mechanism, which remains challenging.…”

PEC-SERS Dual-Mode Detection of Foodborne Pathogens Based on Binding-Induced DNA Walker and C3N4/MXene-Au NPs Accelerator

“…Semiconductor coupling technology is an effective way to improve the photoactivity of materials . As the energy level of MXene and C 3 N 4 match well, coupling C 3 N 4 and MXene to form a heterogeneous structure is conducive to creating a self-driven charge transport channel, thus accelerating the photogenerated carrier migration rate and preventing the recombination of electron holes, which is an ideal strategy for constructing PEC sensors. − Unfortunately, there are few reports about this type of heterostructure in the field of PEC biosensing at present.…”

Cu–Fe bimetallic MOF enhances the selectivity of photocatalytic CO2 reduction toward CO production

“…1–5 However, CO 2 can be converted into energy substances, such as CH 4 , CO, and C 2 H 6 , and other carbon-containing products beneficial to the development of human society through catalytic conversions. 6–14 The catalytic conversion methods involved in this regard mainly include photocatalysis, electrocatalysis, photo-electrocatalysis, and photothermal catalysis. 15–19 Among these, photocatalysis is widely employed by researchers because it is unique as it serves as the artificial simulation of plant photosynthesis.…”
