Resumen de: ZA202403652B

The present invention provides a flower-shaped Bi2CrO6 oxygen-evolving photocatalyst and its preparation method, which belongs to the field of photocatalytic material preparation technology. The method uses bismuth nitrate and potassium chromate as raw materials and employs microwave heating to complete the reaction within a relatively low temperature (100oC) and a short time (2 hs). The preparation method of the present invention is mild, energy-efficient, and requires simple and fast experimental equipment. The obtained Bi2CrO6 photocatalyst samples have uniform size, large specific surface area, and abundant active sites. Additionally, due to the reduced thickness of the flakes, the migration distance of electrons and holes from the semiconductor interior to the surface is shortened, resulting in higher catalytic activity.

SYNERGISTIC BLUE AND GREEN AMMONIA PROCESS

Resumen de: WO2026024621A1

An integrated blue-green ammonia process that avoids the need for air separation is disclosed. Water electrolysis, to produce hydrogen, produces oxygen as a co-product. Natural gas (methane) is reacted in a reformer with steam and air to create a mixture composed primarily of hydrogen, steam, nitrogen and carbon dioxide. The oxygen from electrolysis drives this process, either directly inside an autothermal reformer, or indirectly by oxycombustion in the furnace of a steam methane reformer. The steam is removed by cooling the gas, the carbon dioxide is removed, leaving a purified stream comprising hydrogen and nitrogen. This stream can be combined with additional hydrogen from the electrolyzer to yield a 3:1 mixture of hydrogen and nitrogen for the Haber-Bosch process to make ammonia. The disclosed blue-green process is two-fold less expensive than the conventional green ammonia process and emits about half as much greenhouse gas as the conventional blue ammonia process.
