Porous CuO nanofibers derived from a Cu-based coordination polymer as a photocatalyst for the degradation of rhodamine B

Abstract

Porous CuO nanofibers were synthesized via thermolysis of a Cu-based coordination polymer (Cu-Asp) and exhibit excellent photocatalytic activity towards RhB.

Dimerization of Acetylene to Monovinylacetylene (MVA) by Bimetallic Zr/Cu Catalyst in Nieuwland Catalytic System

“…The H 2 -TPR profile of the fresh NC catalyst revealed two characteristic reduction bands between 400 °C and 696 °C, the Cu 2+ and Cu + in the Cl − rich environment are harder to reduce, as copper ions can form complexes with chloride ions to improve anti-reduction stability, respectively (shown in Figure 4 a) [ 23 , 24 , 25 , 26 , 27 ]. After the reaction (used NC catalyst), the C 2 H 2 destroy the complex formed by copper ion and chloride ion, reduce its reduction temperature, lead to the peak of Cu 2+ and Cu + shifted left.…”

CoP/N‐Doped Carbon Nanowire Derived from Co‐Based Coordination Polymer as Efficient Electrocatalyst toward Oxygen Evolution Reaction

“…The specific surface areas of CoP/NC‐300/400/500 nanowires were calculated to be 60, 117, and 104 m 2 g −1 , respectively. The isotherms are considered to be type IV isotherm, which exhibit the characteristics of mesoporous material. The BJH pore‐size distribution curves further showed different pore sizes for CoP/NC‐300/400/500 nanowires.…”

The enhancement of photocatalytic performance of SrTiO3 nanoparticles via combining with carbon quantum dots

“…h + in the VB of SrTiO 3 can directly oxidize RhB. 56,57 The above analysis indicates that h + and cO 2 À play an important role in the photodegradation process and cOH is not a main reactive species in the photodegradation. On the basis of the above experimental results, a possible photocatalytic mechanism for the CQD/SrTiO 3 nanocomposite is schematically depicted in Fig.…”

“…So the RhB solution was degraded by the photogenerated h + and cO 2 À . 56,57 Therefore, the introduction of the CQDs (electron acceptor) to the SrTiO 3 nanoparticles will facilitate the efficient separation of photogenerated e À -h + pairs and thus enhance the photocatalytic performance.…”
