In the quest for sustainable lignin valorization, the development of efficient catalytic systems for hydrogenolysis of lignin-derived compounds remains a pivotal focus. Utilizing sub-nanometer cobalt catalysts, we achieved the successful...
Lignin transformation into value-added chemicals represents one of the relevant approaches for sustainable development. Here, we prepared and characterized a cobalt (Co-N-C) catalysts and evaluated their activity in transfer hydrogenolysis...
Two‐dimensional (2D) organic–inorganic hybrid perovskites have rapidly become an attractive alternative to three‐dimensional (3D) perovskites as solar cell absorbers, owing to their improved stability, versatility, and ease of processing. Despite their advantages, the insulating nature of the organic cations makes these materials have lower absorbi...
Renewable aromatic carbon sources and their transformation into value-added chemicals represent one of the most promising approaches of sustainable development. Here, we prepared and characterized nickel catalysts and evaluated their activity in transfer hydrogenolysis reactions using formic acid as hydrogen donor, finding excellent activity and hi...
En este trabajo se estudió el mecanismo de activación de un complejo neutro tridentado -N, -O, -S de paladio el cual presentó actividad catalítica hacia la polimerización de etileno. Se realizó una exploración de la superficie de energía potencial del proceso de activación del complejo para entender el origen de su actividad, utilizando la Teoría d...
Two‐dimensional (2D) halide perovskites have recently emerged as a more stable and more versatile family of materials than three‐dimensional (3D) perovskite solar cell absorbers. Although solar cells made with 2D perovskites have yet to improve their power conversion efficiencies to compete with 3D perovskite solar cells, their immense diversity of...
Two dimensional (2D) organic‐inorganic perovskites have rapidly become an attractive alternative to traditional three‐dimensional (3D) perovskites solar cells absorbers due to their improved stability and processability. Despite their advantages, the insulating nature of the organic cations and diminished light absorption limit their overall perfor...

The reaction of carbon dioxide with Et3SiH in the presence of catalytic amounts of [Ru3(CO)12] as a catalytic precursor was achieved to produce silyl formate (Et3SiOCOH) 1s with a TON of 9000. A similar reaction in the presence of KF yielded potassium formate (8s) in a one-pot protocol with high selectivity using water or MeCN as the solvent. In th...
The catalytic conversion of biomass-derived compounds into value-added products such as food additives, agrochemical components, and pharmaceutical formulations, is a promising and cost effective synthetic strategy. Here, we describe the synthesis of a variety of N-(alkyl, aryl)-5-methyl-2-pyrrolidones through the reductive amination of levulinic a...
The selective catalytic hydrogenation and cyclization of levulinic acid (LA) into valuable γ-valerolactone (GVL) catalyzed by different palladium compounds was achieved in water under mild conditions with high yields. Either formic acid (FA) or molecular hydrogen (H2) was used as a hydrogen source. The precatalyst [(dtbpe)PdCl2] (dtbpe = 1,2-(bis-d...
The compound [Ru3(CO)12] was used as precursor for the preparation of ruthenium nanoparticles of a typical size of <5 nm of diameter, without the use of additives. Such nanoparticles catalyzed the hydrogenation and cyclization of levulinic acid to selectively produce γ-valerolactone in high yields, either using molecular hydrogen (H2) or formic aci...
The thermal decomposition of [Ru3(CO)12] allowed the production of ruthenium nanoparticles (NPs) with a unique activity for this metal in the hydrogenation of aliphatic nitriles, yielding the corresponding tertiary amines (selectivity 80%) and aromatic nitriles to secondary amines and imines at 140 °C, employing a moderate hydrogen pressure. The us...
