In this study, activated carbon-supported Sn and Zn oxide catalysts were prepared from hydrolysis lignin used for the conversion of model solutions trioses, hexoses, lignocellulosic biomass hydrolysates to ethyl lactate. Both catalysts, SnO2@AC [email protected], able produce lactate in high yields. was a more active selective catalyst triose (dihydroxyacetone) conversion, providing 99% yield b...

Utilisation and minimisation of spent tyre stockpiles has been made more viable by pyrolysis activation to produce low-cost activated carbons. The unique chemical composition chars (STPC), particularly the high Zn content, shown affect their subsequent utilisation. Nonetheless, little research examined exactly how these additives and, ultimately, what becomes during process. This paper presents...

The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

Developing efficient oxygen reduction reaction (ORR) catalyst is essential for the practical application of Zn-air batteries (ZABs). In this contribution, we develop a novel zeolitic imidazolate framework (ZIF)-mediated strategy to anchor Co species on N-doped carbon nanorods ORR. Featuring ultrahigh N-doping (10.29 at.%), monodisperse nanocrystal decoration, and well-dispersed Co-Nx functional...

Heteroepitaxial Zn-doped p-GaP was grown on (001) GaAs, Si and (111) substrates by hydride vapor phase epitaxy for solar-driven photoelectrochemical applications of hydrogen generation water splitting CO2 reduction. Growth GaP realized through the implementation a low-temperature buffer layer, morphology crystalline quality were enhanced optimizing precursor flows pre-heating ambient substrate....

A series of gold catalysts on ZnO−ZrO2 featuring nominal ZnO loads 3, 5, and 10 wt. % were synthesized by the sol–gel method using Zn(NO3)2 zirconium (IV) propoxide aqueous solutions. In addition, with between 1 3 produced deposition-precipitation urea, their performance in CO oxidation reaction at low temperature was evaluated. HRTEM outcomes revealed high dispersion 3Au/5ZnO−ZrO2 catalyst Zn/...

The hydrogenation of CO2 to CH3OH is mostly performed by a catalyst consisting mainly copper and zinc (Cu/ZnO/Al2O3). Here, Cu-Zn based catalysts are generated using surface organometallic chemistry (SOMC) starting from material isolated ZnII sites dispersed on SiO2 – ZnII@SiO2. Grafting [Cu(OtBu)]4 the silanols available ZnII@SiO2 followed reduction at 500 °C under H2 generates CuZnx alloy nan...

We report an active zinc-copper (Zn-Cu) bimetallic electrocatalyst for CO 2 reduction to CO, prepared by a facile galvanic procedure. Under moderate overpotentials, Zn-Cu catalysts that are Zn rich exhibit intrinsic activity formation superior of pure Zn, Cu, and Ag, the last which is state-of-the-art catalyst in electrolyzers. Combinatorial experiments involving physical vapor deposition revea...

Solvothermal reactions between the polyaromatic group containing carboxylic acid pro-ligands 5-{(pyren-1-ylmethyl)amino}isophthalic (H2L1) and 5-{(anthracen-9-ylmethyl)amino}isophthalic (H2L2) with Zn(NO3)2·6H2O led to formation of new 1D coordination polymer [Zn(L1)(NMF)]n (1) four other polymers, [Zn(L1)(DMF)]n (2), [Zn(L1)(4,4′-Bipy)]n (3), [Zn(L2)(DMF)(H2O)2]n·n(H2O) (4) [Zn2(L2)2(DMF)(CH3O...

We report a high-resolution gas-phase UPS spectrum of zinc phthalocyanine (ZnPc) together with a detailed analysis of the vibronic structure of the first ionization band, showing that presents the lowest value of the intramolecular reorganization energy experimentally reported for a molecular organic semiconductor.
