Molecular catalysts play a significant role in chemical transformations, utilizing changes in redox states to facilitate reactions. To date molecular electrocatalysts have efficiently produced single-carbon products from CO2 but have struggled to achieve a carbon–carbon coupling step. Conversely, copper cat...
Scientists widely use catalysts, which play an important role in chemical production, experiments, and life activities. Some industrial production, such as winemaking and pharmaceuticals, also require catalysts. So the development power of the catalyst is still considerable. ...
Catalysts play a major role in industrial and commercial-scale biodiesel production. Among the various catalysts used in the process, CaO is the most widely studied metal oxide-based catalyst as it gives a high catalytic activity, strong base properties, could be used in relatively low reaction ...

For chemical reactions, response surface methodology (RSM) in conjunction with central composite design (CCD) of experiments can potentially be used to both study the effects of operating parameters and optimize them for maximum yield. The benefits of these methods include a sufficiently small number...
We determined that surface hydroxyl groups of the zeolites, such as Bronsted acid sites, play a role in initiating H spillover, and the Lewis acid sites facilitate the entire process by allowing H to be transferred as a H+/e(-) charge pair, as well as providing good binding sites for ...

Metal particles on various supports play a central role in energy conversion reactions and chemical transformations by heterogeneous catalysis. Ideally, the support immobilizes the particles reducing their mobility to prevent sintering, and favoring chemical stabilization1. Active supports, consisting of redu...
