Biomass-derived carboxylic acids (e.g. acetic acid AcOH and formic FA) are a green low-cost hydrogen source to replace hazardous H2 gas in in-situ hydrogenation processes. To date, bio-acids dehydrogenation has been mainly conducted using noble metal catalysts which would negatively impact the process economy, thus development of efficient non-noble for this purpose is highly desirable. In stud...

The influence of hydrothermal synthesis, thermal post-treatment at 500 °C and Mo content on a series of Bi1-x/3V1-xMoxO4 (0.02 < x < 0.15) photocatalysts was investigated for methylene blue (MB) degradation and O2 evolution. As Mo incorporation stabilizes the formation of tetragonal BiVO4 phases, only calcined Bi0.99V0.98Mo0.02O4 compounds showed good photocatalytic performance in MB decomposit...

A simple, one-step thermal decomposition method for the preparation of Co(3)Mo(3)C is reported in this paper. In this novel synthesis route, a mixed-salt precursor, containing Co(CH(3)COO)(2) x 4H(2)O, (HMT)(2)(NH(4))(4)Mo(7)O(24) x 2H(2)O (HMT = hexamethylenetetramine), and excess HMT is directly decomposed to the bimetallic carbide under flowing argon at 1023 K. The role of HMT in the prepara...

We conducted a 6 year field experiment in an evergreen Quercus ilex forest where we simulated the increased drought projected by Global Circulation Models (GCM) and ecophysiological models for the immediate decades. We tested the hypothesis that enhanced drought will change C, N, P, K, Ca, Fe, Mg, Mo and S concentrations of the widespread moss Hypnum cupressiforme Hedw. and its capacity to abso...

Daylight-driven photocatalysts have attracted much attention in the context of "green" technology. Although various active materials have been reported and their applications are rapidly increasing, many are discovered after enormous experimental efforts. Herein the discovery of a novel oxide photocatalyst, β-SnMoO4, is demonstrated via a rational search of 3483 known and hypothetical compounds...
