2024年1月1日 · Herein, we report the structural, optical, and electrochemical response of Cu 2 Te/CoTe nanoparticles synthesized by the facile microwave synthesis method by varying Cu and Co concentrations.

2024年8月1日 · The hydrothermally synthesized Cu 2 Te exhibited nearly spherical Cu 2 Te nanoparticles (NPs) with orthorhombic structure. The X-ray photoelectron spectroscopy (XPS) confirmed the oxidation states of Cu (+1) and Te (−2) in Cu 2 Te NPs. The band gap of Cu 2 Te NPs is determined from Tauc’s plot as 2.03 eV, suitable as a visible photocatalyst.

2024年4月17日 · Here, ultrathin single-crystalline Cu 2 Te nanosheets as thin as 2.6 nm on SiO 2 /Si and 1.6 nm on a 2D MoS 2 substrate are directly realized by a modified spatially confined chemical vapor deposition (CVD) strategy.

2022年4月15日 · Using a salt-assisted chemical vapor deposition method, we successfully realize the rational synthesis of the high-quality crystal of layered Cu 2 Te nanosheets. The energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy characterizations confirm the chemical composition of our as-grown Cu 2 Te nanosheets.

2023年2月13日 · Here, an in situ vertical growth of scalable metallic 2D Cu 2 Te nanosheet arrays on commercial copper foils is demonstrated for efficient CO 2 -to-CH 4 electrocatalysis. The edge-oriented growth of Cu 2 Te nanosheets with tunable sizes and thicknesses is facilely attained by a two-step process of chemical etching and chemical vapor deposition.

2022年11月15日 · This research is aimed to improve the photovoltaic performance of a device containing Cu2 Te NPs@rGO/Au back contacts. Cu 2 Te NPs, as the active copper diffusion source, dope and passivate the interfaces and grain boundaries of CdTe to form the p +-layer, which can reduce the recombination centers and back-contact barrier height.

2022年3月19日 · In this study, we introduced Cu 2 Te nanoparticles (NPs) into an n-type Bi 2 Te 2.7 Se 0.3 (BTS) matrix to enhance TE performance. Several papers [21, 22, 23] have reported the existence of Cu 2 Te phase when excess Cu is incorporated on Bi-Te-based TE materials. However, they do not discuss the direct effect of Cu 2 Te incorporation.
