Nickel hydroxide (Ni(OH) 2) are promising catalysts for efficient urea oxidation reactions (UOR), which can address the energy and environmental concerns associated with urea-containing wastewater.In addition to their low thermodynamic potential, this reaction can be used for energy-saving hydrogen production instead of the traditional oxygen evolution reaction.
the engineering firm Worley Parsons, and Elizabeth -Gray, CEO of the process technology company Gekko Systems, put down a marker. They argued that advanced comminution circuit design is essential for industry and made the following points. • Electrical energy consumption in comminution has a major impact on the planet's carbon footprint
