“…The coexistence of Cu and Cu 2 O in the synthesized material was also confirmed by use of XRD. The peak at 933.8 eV is due to CuO, although it is slightly higher than the reported energy of CuO (933.7 eV) (Wagner et al, 1979), it agrees well with other values reported for CuO surface phase (Wagner et al, 1979;Espinós et al, 2002;Zhu et al, 2004;Wang et al, 2003Wang et al, 2002Xu et al, 1999;Hui et al, 2002;Brookshier et al, 1999;Fernando et al, 2002). The, three peaks of 530.2, 531.6, 533.6 eV observed in the O1s spectrum (Fig.…”

• We present an effective catalyst for reductive degradation of organic dyes and phenols in water.• Compared with noble metals, Cu/Cu 2 O/ CuO@C particles are more efficient and less expensive • The porous structure provided a large contact area and channels for the pollutions and active site. , infrared spectroscopy and Raman analysis, revealed that it was composed of graphitized carbon with numerous nanoparticles (100 nm in diameter) of Cu/CuO/Cu 2 O that were uniformly distributed on internal and external surfaces of the carbon support. Gallic acid (GA) has been used as both organic ligand and carbon precursor with metal organic frameworks (MOFs) as the sacrificial template and metal oxide precursor in this green synthesis. The material combined the advantages of MOFs and Cu-containing materials, the porous structure provided a large contact area and channels for the pollutions, which results in more rapid catalytic degradation of pollutants and leads to greater efficiency of catalysis. The material gave excellent catalytic performance for organic dyes and phenols. In this study, Cu/Cu 2 O/CuO@C was used as catalytic to reduce 4-NP, which has been usually adopted as a model reaction to check the catalytic ability. Catalytic experiment results show that 4-NP was degraded approximately 3 min by use of 0.04 mg of catalyst and the conversion of pollutants can reach more than 99%. The catalyst exhibited little change in efficacy after being utilized five times.

“…The cleaned powder was dispersed in a 10 −3 M CuSO 4 solution and boiled for 1 h to obtain Cu 2 O layers on the surface of each particle. 1 h of boiling was reported to be an optimum period after which the dissolution of Cu 2 O was observed [22], a fact attributed to the increase of the media acidity. This technique allows to obtain Cu/Cu 2 O heterosystem.…”

“…Without it, the early studies had to rely on Schottky junctions and p-n heterojunctions for photovoltaic devices, which do not provide high efficiency. However, Fernando et al, 2002, has reported the possibility of obtaining n-type photoresponses from clean copper plates, immersed in CuSO 4 solution for a few days. Subsequently, the same researchers reported the n-type Cu 2 O produced by heating copper sheets in CuSO 4 solution.…”

“…It was shown that the PV properties of Cu 2 O Schottky cells are significantly affected by the surface treatment and crystallinity of Cu 2 O (Fernando et al, 2002 andTanaka et al, 2004). In particular, the deposition method and conditions are important when depositing a thin film on Cu 2 O sheets.…”
