Preparation of a TNTs / NiO@CoPi array electrode for photoelectrocatalytic decomposition of water
This invention discloses a method for preparing a TNTs / NiO@CoPi array electrode (TNCP) for photoelectrocatalytic water splitting, belonging to the field of photoelectrocatalytic new energy materials technology. The invention first prepares a highly ordered anatase TiO2 nanotube array (TNTs) using secondary anodic oxidation, then loads Ni nanoparticles onto the surface and inside the nanotubes via constant current electrodeposition, followed by high-temperature calcination to generate p-type NiO, constructing a TNTs / NiO p-n heterojunction (TN). Finally, it uses AM 1.5 simulated sunlight to selectively deposit an amorphous CoPi cocatalyst, where the CoPi only coats the NiO nanospheres without blocking the TiO2 mass transfer channels. This invention utilizes the p-n heterojunction to broaden the full-spectrum light absorption from 250 to 800 nm, and CoPi acts as a hole-trapping layer to suppress electron-hole recombination, significantly reducing interfacial charge transport impedance; the steady-state photocurrent of the TNCP deposition sample reaches 0.06 mA·cm⁻. 2 It is three times that of pure TNTs. This process involves no precious metals or highly toxic corrosive solvents, and the reaction conditions are mild. The electrodes produced can be used for photoelectric water splitting to produce hydrogen, photoelectric oxidation of organic pollutants, and ethylene glycol photoelectric fuel cells.

This application provides an ultrasonic-assisted forming method for capillary glass tubes used in optical inspection, applied to a forming apparatus including an ultrasonic base and a metal core needle. After preheating the forming apparatus to a first temperature, molten glass is poured in, causing it to coat the core needle and tend to form a transiently solidified layer. An acoustic model is established by collecting the effective working length of the core needle and the material's acoustic parameters. Based on the acoustic model and considering the critical energy density required to destroy the transiently solidified layer and the effective glass forming time, the acoustic energy output parameters of the core needle are determined. According to these parameters, high-frequency ultrasound is continuously applied through the ultrasonic base during the cooling process of the glass from the molten state to a second temperature, causing the core needle to vibrate to destroy and suppress the transiently solidified layer. The ultrasound is then turned off. This method can reduce interfacial stress concentration, suppress the formation of microcracks on the inner wall, and improve the smoothness of the inner wall of the capillary glass tube as well as its optical and mechanical properties.
