A catalyst for chemical reactions of the carbon monoxide, which is more particularly applicable for the preparation of the hydrogen and of methyl alcoholGRENIER RENE-JEAN-AUGUSTE
given that he was one of the early dissenters who brought it about. In the 1980s he championed the idea that RNA molecules can also act as enzymes—that is, as catalysts for biochemical reactions—a claim which flew in the face
The ever-increasing demand for efficient and sustainable catalytic systems has prompted a surge in the exploration of transition metal nanoparticles as catalysts for various chemical reactions. Among these, copper-based nanoparticles have emerged as promising contenders, offering a viable alternative to the...

The catalyst exhibited excellent activity for promoting various chemical reactions, including Knoevenagel condensation, synthesis of xanthan and octahydroquinazolinones in aqueous media under ultrasonic irradiation. It was believed that CD in the framework of the catalytic composite acted as a molecular ...

As such, perovskites provide rich opportunities to tune their chemical, physical, and catalytic properties. A superior catalyst for 2e-WOR must meet the following three requirements: (i) high stability to fulfil the demand for long-term operation; (ii) high selectivity to prevent the formation ...
