Improved hydrogen production performance of an S-scheme NbO/LaO photocatalyst.

Addressing the intricate challenge of simultaneously improving the separation of photoinduced electron-hole pairs and enhancing redox potentials to produce hydrogen fuel demands the rational design of S-scheme heterojunction photocatalysts. Herein, we used a hydrothermal process to integrate NbO nanorods and LaO nanosheets to design an NbO/LaO S-scheme system for photocatalytic hydrogen production under simulated sunlight illumination. Notably, the optimal hydrogen production performance of NbO/LaO (the molar ratio of NbO to LaO is 0.

Thermal-hydraulic characteristics of nitric acid: An experimental and numerical analysis.

Nitric acid is one of the most important products in the chemical industry, ranking third globally in terms of acid production. Although nitric acid has many industrial applications, its primary function is the production of ammonium nitrate, which is used in the fertilizer industry. In this report, we propose a plan for an Ostwald process plant that will produce 1000 metric tons of nitric acid per day.
