In the present study, we examined the catalytic activity of Ru-based cocatalysts for IO acceptor, which is an important half component in Z-scheme water splitting systems.On 09 August 2017 NNSA (National Nuclear Safety Administration of China) issued official permit for the loading of nuclear fuel into the reactor of power unit No 3 of Tianwan NPP.

The physical start-up stage will commence in the nearest future - the first fuel assembly will be loaded into the reactor, said Alexey Bannik, JSC ASE EC Director for projects in China.

Totally 163 fuel assemblies will be loaded into the reactor.

It also facilitates a fine-tuning of the electrocatalyst’s activity and selectivity by changing the coverage (the cluster size) of Pt for optimal performance under required CO tolerance levels.

Loading an appropriate cocatalyst significantly enhances the activity of semiconductor photocatalysts in both conventional one-step water splitting and Z-scheme-type water splitting with a redox couple.

While platinum (Pt) nanoparticles are highly active catalysts for both HER and HOR, the scarcity and high cost of Pt impede large-scale commercialization of these clean energy technologies.

Our approach controls core-shell structure at the atomic level to maximize the Pt specific surface area and to improve catalytic performance through core-metal-induced effects.

Although such solar thermochemical conversions would increase natural gas product yields and reduce greenhouse gas emissions, current costs of solar facilities are prohibitively high.

Parabolic troughs, which are a mature and relatively inexpensive form of solar concentrator, are limited to temperatures of ca. In this regime, commercial methane steam reforming Ni-based catalysts have low activity and rapidly deactivate due to oxidation and coking.

The method offers a unique possibility to place the Pt atoms onto the surface of Ru nanoparticles, which very likely makes almost all of them available for hydrogen oxidation, in contrast to the Pt-Ru alloy catalysts that have Pt throughout the nanoparticles.

Thus, an ultimate reduction of Pt loading can be achieved.

Catalysts based on platinum group metals are much more active and stable but their high cost limits their use.
