The direct hydrogenation of CO2 to higher alcohols has the potential turn main contributor global warming into a valuable feedstock. However, for this technology become attractive, more efficient and, especially, selective catalysts are required. Here we present high throughput study on influence different promoters performance Rh−SiO2 catalysts. Fe and K were found improve ethanol selectivity ...

The utilization of perovskites as photocatalysts to convert CO2 into fuels and chemicals has received wide attention recently. However, their instability in water hinders long-term application for overall photocatalytic reduction. Herein, we integrate the water-stable perovskite-like organolead iodide crystalline material [Pb8I8(H2O)3]8+[−O2C(CH2)4CO2−]4 (TJU-16) with Au co-catalyst reduction a...

an extensive study of higher alcohols synthesis (has) from syngas using alkalized mos2 catalysts supported on carbon nanotubes (cnts) is reported. up to 30wt.% of mo and 8wt.% k are added to the cnts by impregnation method. the catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. tem images showed that most of the metal particle...

Alman ceza hukukunda intihar etmek suç değildir. Suç olmayan bir eyleme iştirak edenler de hukukundaki bağlılık kuralı gereğince cezalandırılamaz. Ancak kamuoyunda ve bilim çevrelerinde intihara yardım niteliğindeki bazı eylemlerin cezalandırılması gerektiği konusu, yoğun olarak tartışılmaktadır. Bu tartışmalar neticesinde 2015 yılında, belli eylemler Ceza Kanunu’nun 217. paragrafı ile cezai ya...

In the present work, the transformation of m-xylene was studied over fresh and pre-coked HZSM-5 catalyst in a riser simulator over the temperature range of 350-500C.Significant differences were observed in both the activity and product selectivity pattern for the two forms of the catalyst. While, the fresh catalyst generally gave higher m-xylene conversion, the pre-coked catalyst produced highe...

The overall objective of this grant is to develop a rational framework for the discovery of low cost, robust, and active nano-catalysts that will enable efficient hydrogen production. Our approach will be the first demonstration of integrated multiscale model, nano-catalyst synthesis, and nanoscale characterization assisted high throughput experimentation (HTE). We will initially demonstrate ou...

A triethylaluminium(TEAl)-modified Phillips ethylene polymerisation Cr/Ti/SiO2 catalyst has been developed with two distinct active regions positioned respectively in the inner core and outer shell of the catalyst particle. DRIFTS, EPR, UV-Vis-NIR DRS, STXM, SEM-EDX and GPC-IR studies revealed that the catalyst produces simultaneously two different polymers, i.e., low molecular weight linear-ch...

Here, we have synthesized vertically aligned carbon nanotubes (VA-CNTs), using chemical vapor deposition (CVD) method. Cobalt and ethanol are used as the catalyst and the carbon source, respectively. The effects of ethanol flow rate, thickness of Co catalyst film, and growth time on the properties of the carbon nanotube growth are investigated. The results show that the flow rate of ethanol and...

Platinum group metal-free (PGM-free) catalyst with different loadings was investigated in air breathing electrodes microbial fuel cells (MFCs). Firstly, the electrocatalytic activity towards oxygen reduction reaction (ORR) of the catalyst was investigated by rotating ring disk electrode (RRDE) setup with different catalyst loadings. The results showed that higher loading led to an increased in ...
