Herein, we report the results of in-situ synthesis of four different metal(0) nanoparticles (Pd, Cu, Ru, and Ni) loaded on the surface of cellulose (MNPs@Cellulose) and their catalytic use in the solventless dimethylamine-borane (DMAB) dehydrogenation at 35.0+0.1°C were reported. Additionally, detailed kinetic studies on the solventless DMAB dehydrogenation...

In this paper, the effect of alkali metal deposition on the activity of x-Co3O4 (x = Na, K, Rb, Cs) catalysts for the N2O catalytic decomposition was explored by DFT calculation and various experimental characterization methods. The results demonstrated that the deposition of alkali metal Na improved the activity of the Na-Co3O4 catalyst for N2O catalytic...

N-doped mesoporous carbon spheres were synthesized by a microwave-assisted ammonia-catalyzed hydrothermal route (CFAHM) by using Pluronic® F127 as a soft-template and m-Aminophenol as both carbon and nitrogen source. Their physical and electrochemical properties were compared with those of carbon samples obtained by a conventional hydrothermal method...

This paper aims to describe and validate two cells designed to monitor, by in situ quick-EXAFS, the transformation of Mo based oxidic species occurring during maturation and drying preparation steps of a single hydrodesulfurization catalyst. These transformations occur firstly upon impregnation/maturation, due to the contact of the acidic impregnation...

The capture and conversion of anthropogenic CO2 is a paramount challenge for our global ecosystem. An optimal way of to cope with the emitted CO2 is to efficiently convert it to value-added materials. Whereas nature sequesters CO2 by making sugar-based polymers, utilizing CO2 to make highly demanded synthetic polymers such as polycarbonates is of great...

Electrochemical nitrogen reduction reaction (NRR) under ambient conditions offers an environmentally benign and sustainable alternative for NH3 synthesis. Exploring highly active and robust NRR electrocatalysts is one of the prerequisites for developing sustainable N2/NH3 cycle systems. In this work, a surface chemistry rich TiO2/CeO2 frame is developed...

Viable routes for the bioproduction of commodity chemicals need to operate at low profit margin and bulk scale, but product toxicity frequently limits in vivo yields. A robust method for production of pure styrene from L-Phe rich biomass using whole-cell biocatalysts is presented, bypassing toxicity problems. This strategy can be applied to access other...

Nitrogen Nucleophiles: A general method for direct N-acylation of less nucleophilic nitrogen heterocycles with carboxylic acids is reported. The method, which uses simple, commercially available reagents, no metals and user-friendly conditions, shows excellent functional group tolerance and broad substrate scope for both nitrogen nucleophiles and carboxylic...

A new series of catalysts for the hydrogenation of CO2 to formate were developed. They are based on ligand-capped Pd nanoparticles synthesized in presence of supports of different nature. Catalysis experiments were carried out using water as solvent and in presence of a base. PPh3 as ligand gives best results with a TON of 1032 (TOF of 69 h−1). ...

High OER/ORR performances: boosted oxygen reduction reaction (ORR) as well as optimized oxygen evolution reaction (OER) and high-activity zinc-air batteries (ZAB), from a nitrogen-doped carbon nanomaterial (NCM) inserted Ni−Co layered double hydroxide (NiCo-LDH) electrocatalyst on nickel foam are achieved. The super thin NCM prepared by calcination...
