This perspective illustrates the electromagnetic induction heating technology for a rational heat control in catalytic heterogeneous processes. It mainly focuses on remarkable advantages of this approach terms process intensification, energy efficiency, reactor setup simplification, and safety issues coming from use radio frequency heated susceptors/catalysts fixed-bed reactors under flow operational conditions. is real enabling that allows to go beyond bounds, reducing inefficient transfer...
Abstract Visible‐light photocatalytic carboxylation with CO 2 is highly important. However, it still remains challenging for reluctant substrates low reduction potentials. Herein, we report a novel of C−N bonds in cyclic amines via consecutive photo‐induced electron transfer (ConPET). It also the first reductive ring‐opening reaction azetidines, pyrrolidines and piperidines.

Mn-promoted Ni nanoparticles (NPs) supported on oxygen-functionalized carbon nanotubes (CNTs) were synthesized for CO2 hydrogenation to methane. This novel metal-carbon catalytic system was characterized by both experimental and computational studies. An anomalous metal-support interaction mode (i.e., a higher temperature would lead weakened Ni-CNT interaction) observed. Deep investigation confirmed that surface oxygen groups (SOGs) CNTs played key role in tuning the interaction. We proposed...
Carbon dioxide (CO2) hydrogenation to methane (CH4) is a way of great significance from an energy-saving viewpoint that consists in the direct conversion natural and abundant waste into fuel added value. Indeed, it can be used provide synthetic CH4 as alternative source gas potentially injected existing grid. This contribution describes synthesis robust catalyst for efficient selective CO2 methanation, based on Nickel nanoparticles (Ni-NPs) grown N-doped carbon nanotubes (Ni/N-CNT). The high...
Carboxylation with CO2 offers an attractive and sustainable access to valuable carboxylic acids. Among these methods, direct C−H carboxylation of terminal alkynes has attracted much attention for one-carbon homologation alkynes, enabling rapid synthesis propiolic In contrast, the multi-carbons construct important non-conjugated alkynyl-containing acids not been reported. Herein, we present alkynylcarboxylation alkenes via photoredox copper dual catalysis. This protocol provides a practical...
Abstract Bio‐inspired and cost‐effective development of highly porous foam‐like carbon structure originating from waste fig‐fruit raw materials using chemical activation is described.

Abstract The porous silicon carbide (β‐SiC) carrier supported nickel‐lanthanum based catalysts (NiLa/SiC) were synthesized via incipient‐wetness impregnation by using two types of nickel salts as the precursor, for selective hydrogenation carbon dioxide (CO 2 +4H →CH 4 +2H O). alumina also prepared and tested comparison. samples characterized TEM, TPR, XRD, SEM, TG‐DTG techniques. Compared to Al O 3 catalysts, SiC more resistant sintering deposition due high thermal conductivity support....
