Cu2-xS@ZnCdS显示高她光催化活性8175 μmol h−1g−1,是1168倍和3.1倍Cu2-xSZnCdS,分别在可见光照射下,特别是表观量子产量(AQYs)Cu2-xS@ZnCdS在420 nm为10.2%。与现有的ZnCds基和Cu2-xS基光催化剂相比,在光催化中表现出优越的性能。原位x射线光电子能谱(XPS)和电子顺磁共振(EPR)分析表明,高活性和...
XPSinvestigationInteraction of a non-stoichiometric copper sulphide (Cu2−xS) coating chemically formed on glassy carbon with Ag+ ions as well as the electrochemical behaviour of the coating obtained were investigated in 0.1 M NaOH and 0.05 M H2SO4 solutions by using cyclic voltammetry and X-...
Chemical states of the Cu single atom and its interaction with TiO2 are systematically explored by XPS. In the XPS of Cu 2p (Fig. 2e), four deconvoluted peaks are attributed to Cu2+ (∼953.9 and 933.9 eV) and Cu+ (∼951.6 and 931.9 eV), accompanying a satellite peak resulted from...
Fig. 1: A multifunctional theranostic platform based on BP@Cu hybrid nanomaterial. Inset box: illustration of the composition and construction of the BPNS-based nanomaterials. The biological responses elicited by the synergistic therapeutic effects of BPNS and Cu ions are illustrated. The BPNS is cou...
Figure 1 High resolution (a) Cu2p, (b) Mn2p, (c) O1s, and (d) S2p XPS spectra of CuMnOS-0 and CuMnOS-3. Full size image Figure 1b shows the high resolution Mn2p XPS spectra of CuMnOS-0 and CuMnOS-3. The peak separation of 11.5 eV between Mn2p3/2 and Mn2p1/2 locat...
The D-band to G-band intensity ratio (ID/IG) of the samples is calculated to be around 1.07, implying the limited graphitization degree of Cu2−xS/CNFs. Figure 5. XPS survey spectra (a) of Cu2−xS/CNFs. High-resolution (b) Cu 2p and (c) S 2p XPS spectra for Cu2−xS/C...
XPS analysis of CuIn(S1xSex)2 thin films prepared under optimized conditions revealed the absence of binary secondary phases. However, Cu2S or CuS was found to be secondary phase in CuIn(S0.5Se0.5)2 thin films. 展开 关键词: XPS AES CuIn Se_xS_(1-x) solar cell thin films binding ...
First succesfull attempts to apply ZnS-CuInS2 mixed crystals in double heterojunction p-i-n solar cells in combination with AgIn5S8 and CuI are presented. Besides of studying the optoelectronic properties of the heterojunction structures, a special attention is paid to the problem of optimal band ...
XPS was performed on an ESCALAB 250Xi ultrahigh vacuum (UHV) source (1486.6 eV). A thin surface analysis film was formed system (Thermo Fisher Scientific) with a monochromic Al by drop-casting the sample solution on single crystal silicon KsuαbXst-rraatye for measurement. Electrochemical ...
In order to form a kesterite absorber suitable for soof ltahrecCelul 2a−pxpSlnicaantoiopnasr,titchlee as-deposited CZTS thin-films must undergo a final sulfurization process whereby the films, along with S and SnS pellets, are placed together in a atmosphere at a pressure of 60 graphite...
