Fabrication of novel p-CuO/n-ZnO heterojunction nanofibers by electrospinning for enhanced photocatalytic performance in the denitrification of fuel oil

Mixed valence copper oxide composites derived from metal–organic frameworks for efficient visible light fuel denitrification

“…The two characteristic peaks at 952.5 and 932.8 eV correspond to the binding energies of Cu + 2p 1/2 and 2p 3/2 electrons, while the two characteristic peaks at 953.8 and 933.8 eV correspond to the binding energies of Cu 2+ 2p 1/2 and 2p 3/2 , respectively. 46,47 In addition, satellite peaks with 2p 1/2 and 2p 3/2 peaks were also observed, corresponding to the electronic oscillation, 48 indicating the presence of Cu 2+ and the coexistence of Cu 2 O and CuO on Cu x O-T. It can be found that in Cu x O-T, the ratio of Cu + /Cu 2+ gradually decreases with the increase in temperature, and the ratio of Cu x O-300 is the highest at other temperatures, while Cu x O-500 is the lowest.…”

Hierarchical 0D CuO Wrapped by Petal-like 2D ZnO: A Strategic Approach of Superhydrophobic Melamine Sponge toward Wastewater Treatment

“…To enhance the photocatalytic activity, creating a heterojunction involving n-type and p-type semiconductors emerges as a viable and effective approach. 37 Copper oxide (CuO), an outstanding p-type semiconductor characterized by a narrow band gap and visible light response, is well suited for forming p−n heterojunctions with ZnO. 38 Several studies have explored CuO/ZnO p−n heterojunctions to improve photocatalytic activity, primarily focusing on the elimination of water-based pollutants.…”

Amino-functionalized MIL-125(Ti) for photodenitrification of pyridine in fuels via coordination activation by unsaturated Ti4+ centers

“…Fossil fuels, such as diesel and gasoline, are significant and precious global energy resources. 1 Riding the wave of industrialization, massive gasoline fuel consumption brings environmental pollution and human health hazards. NO x resulting from the combustion of nitrogen-containing compounds (NCCs) in fuels, has become one of the most severe environmental problems.…”
