The oxidation of methane, the main component of natural gas, to selectively form oxygenated chemical feedstocks using molecular oxygen has been a long-standing grand challenge in catalysis. Here, using gold nanoparticles supported on the zeolite ZSM-5, we introduce a method to oxidize methane to ...
In light of the effects, we propose that the bifunctional interaction between Pt and Ni(OH)2 may present a possible solution to the long-standing durability issue in MOR electrocatalysis. Here we report the design and electrocatalytic performance of Pt-Ni(OH)2–graphene ternary hybrids for ...
Doping in the consolidated state also allows one to achieve a gradient of antioxidant in consolidated polymeric material. One can dope a certain thickness surface layer where the oxidation of the polymeric material in a medical device is of concern in terms of wear. This can be achieved by simp...
and Israel E. Wachs (ChE, Principal Investigator) used a multitude of characterization techniques to solve this long-standing debate with Infrared (IR) and Raman spectroscopy, High Resolution Transmission Electron Microscopy (HRTEM), Temperature Programmed Surface Reaction (TPSR) spectroscopy and steady...
The grey dashed line represents the B/TM ratio of a stoichiometric TMB2 coating material. Numbers denote the quantity of Si platelets used to obtain the composition. (b) Hardness determined using nanoindentation for all coatings in the as deposited state. Nevertheless, by adding Si in the ...
Although it has been demonstrated that multinuclear active sites are commonly necessary for water oxidation, as inspired by the natural oxygen-evolving centre CaMn4O5, a multinuclear manganese cluster, whether mononuclear manganese can also efficiently catalyse water oxidation has been a long-standing ...
However, the synthesis of Pt NCs with definite Pt atom number and decent surface chemistry is a long-standing challenge in the cluster research community. This is most probably due to the vibrant catalytic activity of freshly generated Pt atoms that induce in-situ deposition and catalytic decomposi...

Using the transition state search method corrected with working potentials relative to the reversible hydrogen electrode (RHE), we further calculated the activation barrier of each elementary step for Pt (111) and Au
photosensitization occurs when compound reacts to the excited state of the sensitizer, which leads to the formation of radicals or radical ions through electron transfer or hydrogen atom, but in the case of type II photoreaction, the excited sensitizer reacts with oxygen for forming a singlet ...
