Synthesis of cuprous oxides thin film with different morphologies by electrodeposition

Abstract

Cuprous oxides thin film with different morphologies were formed on F-doped tin oxide (FTO) covered glass substrates by potentiostatic deposition of cupric acetate. The effects of electrodeposition temperature and Bron the crystal morphologies of cuprous oxide were studied. Different crystal morphologies of cuprous oxides were obtained by the change of electrodeposition temperature or the concentrations of Br-. The network-like and tetrahedron morphologies of Cu 2 O crystals were obtained when using higher deposition temperature and concentration of KBr, respectively. Photoelectrochemical behavior of the cuprous oxides thin films prepared in the system was also studied.

Substrate Effect on Liquid Petroleum Gas Sensors of Cuprous Oxide Thin Films Electrodeposited in Acetate Bath

“…At some point (response time), this process reaches its equilibrium. [39][40][41] As emphasized in Fig. 9, Cu 2 O film on ITO has the most significant LP gas response with a maximum of 32.63 at 70 °C.…”

Performances of Nano-Structured Cu2O Thin Films Electrochemically Deposited on ITO Substrates in Lactate Bath as Liquid Petroleum Gas Sensors

“…[6][7][8][9][10][11][12][13][14][15][16][17][18][19] Cuprous Oxide (Cu 2 O) is an ideal material for researches due to its advantageous in non-toxicity, mechanical, electrical, and catalytic properties and the natural abundance of the base material. [20][21][22][23][24][25][26][27][28] At present, a variety of techniques exist to synthesize Cu 2 O with different microstructures on selected substrates, including thermal oxidation with copper sheets at 200 °C/1050 °C, chemical vapor deposition with alumina slides at 300 °C, magnetron DC sputtering on glass at 693 K, radio, anodic oxidation on glass at 280 °C29-33 etc. However, in many respects, such as ease of film fabrication and low cost, low processing temperature, controlled crystallization with surface morphology, roughness, and wettability in a large area, high deposition rate, 34 Cu 2 O thin films produced by electrochemical deposition are highly suitable for gas sensors, solar cells, photo-electrochemical cells, and catalytic applications.…”
