Fabrication of an S-Scheme Heterojunction Photocatalyst MoS2/PANI with Greatly Enhanced Photocatalytic Performance

“…As depicted in pathway II, NOR is oxidized and piperazinyl ring-opened to form N2 ( m / z = 350), and subsequently produce N3 ( m / z = 279), N4 ( m / z = 261), and N5­( m / z = 233) owing to the subsequent partial elimination of −OH, −C 3 H 6 N, −F, and −CO, respectively. , In pathway III, NOR mainly involves the quinolone ring opening caused by the ·OH attacking on the C–C adjacent to carboxylic acid group accompanied/unaccompanied by defluorination or hydroxylation, resulting in formation of N6 ( m / z = 350). The following products of N7 ( m / z = 295) and N8 ( m / z = 225) produce by piperazine ring-rupturing reactions . NOR can be further degraded into small molecules of N9 ( m / z = 118) and finally mineralized to CO 2 , H 2 O, F – , and NO 3 – . − …”

An innovative S-scheme PhC2Cu/Ag/Ag2MoO4 photocatalyst for efficient degradation of sulfamethazine antibiotics: heterojunctions and innergenerated-H2O2 promote radical production

“…The CB values of the AMO was determined to be −0.27 V via Mott–Schottky measurement, as shown in Fig. S7b,† the corresponding VB potential value of the AMO were calculated as 3.08 V vs. NHE based on the eqn (4) and (5): 17 E NHE = E SCE + 0.24 E CB = E VB − E g …”

“…Copper-phenylacetylide (PhC 2 Cu) is an advanced metal organic polymer with a broad visible light response, while its long range ordered copper-copper ladders and subunit-packing geometric structure can provide highly organized unidirectional electron transport pathways and more efficient active sites. [14][15][16][17] In addition, PhC 2 Cu has an excellent capacity for the generation of H 2 O 2 , 16 which may endow compounded materials with great potential to innergenerated-H 2 O 2 . However, PhC 2 Cu still suffers from a low valence band (VB = 0.24 eV) and rapid electron hole/pair (e − -h + ) recombination.…”

Embedding CsPbBr3 Quantum Dots into an In2O3 Nanotube for Selective Photocatalytic CO2 Reduction to Hydrocarbon Fuels

“…Under dark conditions, no characteristic signal peaks were observed for 5,5-dimethyl-1-pyrroline N -oxide (DMPO)– • O 2 – and DMPO– • OH. Upon light irradiation, the characteristic peak of DMPO– • O 2 – emerges, and the peak intensity increases with increasing irradiation time. , Furthermore, to reveal the oxidation ability of the CPB/IO catalyst, the oxygen evolution reaction (OER) in Na 2 SO 4 was measured through linear sweep voltammetry (LSV) curves. As shown in Figure S7, the current density of all catalysts increased under illumination, indicating the important role of light in the generation of photogenerated carriers.…”
