Tuning metal-support interaction has been considered as an effective approach to modulate the electronic structure and catalytic activity of supported metal catalysts. At atomic level, understanding structure-activity relationship still remains obscure in heterogeneous catalysis, such conversion water (alkaline) or hydronium ions (acid) hydrogen (hydrogen evolution reaction, HER). Here, we reveal that fine control over oxidation states single-atom Pt catalysts through significantly modulates...
Dry reforming of methane is a promising chemical reaction that can utilize CO2 and natural gas to produce value-added feedstocks. However, this process's commercialized implementation has been stalled due the lack excellent durable reusable catalysts. Here, we report pseudo-binary alloy (Ni0.5Co0.5)3Ge/SiO2, which partially substitutes Ni with Co without altering parent Ni3Ge phase. The combination high-angle annular dark-field–scanning transmission electron microscopy–energy-dispersive...
Using ball milled CNT catalysts, the electrocatalytic reductive amination of keto acids to amino was efficiently conducted. Moderate high formation rates (up 180.9 mmol g −1 cat h ) and Faradaic efficiencies 90%) were achieved.
Abstract Production of value‐added chemicals from lignocellulose is one the key strands emerging bio‐economy. A synthetic approach has been developed to produce p ‐methoxy coumarate esters waste corn stover and bran, further transform these compounds into consumer products. In first step, ‐coumaric acid ( CA) ferulic (FA) are released through mild alkaline hydrolysis waste, in more than 20 mg g −1 yield (10 wt % based on lignin content). Subsequently, heterogeneous solid acids catalyze...
Microbial fermentation of lignocellulosic materials is a promising avenue for sustainable production amino acids. Conventional microbes used in acid consume sugars derived from hydrolysis cellulose and hemicellulose leave the lignin component unutilized. However, contains up to 12% p-coumaric (pCA) by weight, which can be recovered during alkaline pretreatment potentially produce l-tyrosine. In this study, we explored route l-tyrosine pCA it parallel with conventional microbial form an...
Despite the increasing interest on electrocatalytic refinery of renewable feedstocks to produce value-added chemicals, nitrile electrosynthesis from alcohols is rarely studied. Here, we report direct nitriles primary and ammonia, with a simple nickel catalyst under benign conditions in aqueous electrolytes. The highest benzonitrile faradaic efficiency 63.0% was achieved at 1.375 V vs. RHE. reaction proceeds via dehydrogenation-imination-dehydrogenation sequence, rate-determining step likely...
With the availability of very high resolution commercial satellite data, there has been much interest to extract man-made objects from such imagery. We propose a PC-based incremental system, which includes both road and building extraction tasks in same package, makes use IKONOS's stereo pair generate 3-D city-model. For each image set, we first traditional Normalized Difference Vegetation Index (NDVI) locate vegetated areas be used for masking, apply Canny operator panchromatic images edge...
Despite increasing interest devoted to the electrocatalytic refinery of renewable feedstocks for sustainable production value-added chemicals, direct electrosynthesis nitriles from biomass-derived alcohols is rarely studied. Nitriles are highly versatile intermediates producing a wide range including biological materials, pharmaceuticals and polymers. The conventional chemical methods nitrile synthesis, such as Sandmeyer Rosenmund-von Braun reactions, not benign they utilize toxic starting...
Despite increasing interest on the electrocatalytic refinery to produce value-added chemicals, heterogeneous nitrile electrosynthesis from alcohols is still in initial stage of investigation. Here, we report direct electrosynthesis...
