Nowadays, catalytic hydrogenation and hydrogenolysis reactions of renewable biomass and its downstream products, e.g., carbohydrates and platform chemicals in aqueous media are key unit processes in a biorefinery and presents a highly active research field for the development of new processes to manufacture advanced biofuels, bulk and value-added fine chemicals, solvents, materials, pharmaceuticals and even foodstuffs, e.g., trans-free edible fats.
Aqueous-phase catalysis is consistent with six of the twelve principles of Green Chemistry (low E-factors, i.e., high atom economies; use of innocuous solvents; renewable feedstocks; catalytic reagents; designing safer chemicals; inherent safer chemistry especially in exothermic hydrogenation reactions due to the high heat capacity of water) and could play a major role to achieve sustainability in industrial-scale catalytic processes. The highly polar aqueous solvent is the ideal medium to carry out catalytic hydrogenolysis and hydrogenation reactions because of the polarity of biomass and of biomass-derived compounds and enormously accelerates the reaction rates in comparison to organic solvents which is shown by numerous experimental and theoretical investigations, e.g., in the levulinic acid and furfural hydrogenation reactions.
This Special Issue welcomes reports on recent advances in aqueous-phase (transfer) hydrogenation, hydrogenolysis and hydrotreating namely hydrodeoxygenation, hydroisomerization (dewaxing), hydrodecarbonylation and hydrodecarboxylation reactions of all kinds of biomass (lignocellulose, vegetable and tropical oils, fats, terpenes, algae) and all its downstream products (carbohydrates, polyols, triols, e.g., glycerol, diols, aromatic compounds and other platform chemicals such as levulinic acid, furfural, 5-hydroxymethylfurfural, succinic acid, etc.) using homogeneous coventional as well as water-soluble catalytic complexes of noble or non-noble metals, biocatalysts, conventional heterogeneous systems, noble or non-noble metal(0) catalytic nanoparticles immobilized on the surface of different solid supports as well as water-dispersible metal(0) catalytic nanoparticles stabilized by polymers in aqueous monophasic, aqueous/organic two-phase systems, micellar systems, thermoregulated phase-transfer systems, emulsions and microemulsions. Emphasis will be also placed in the direct, one-pot catalytic hydrogenolysis reactions of raw biomass without separation of cellulose, hemicellulose and lignin and purification of the platform chemicals to obtain industrially relevant intermediates, fuel alkanes and ethanol. Furthermore, this Special Issue also encourages reports on the aqueous-phase catalytic hydrogenation of biomass-derived CO2 to various chemicals. Within the scope of this Special Issue are all aspects related to these catalytic reactions, e.g., development and characterization of new catalysts, physico-chemical, mechanistic and theoretical investigations, reactor engineering, recovery and recycling of catalysts and scale up of the reactions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
