Nanostructured β‐Bi 2 O 3 Fractals on Carbon Fibers for Highly Selective CO 2 Electroreduction to Formate

Metal-free boron-doped graphene for selective electroreduction of carbon dioxide to formic acid/formate.

Herein we report the electrocatalytic activity of boron-doped graphene for the reduction of CO2. Electrolysis takes place at low overpotentials leading exclusively to formate as the product (vis-à-vis benchmark Bi catalyst). Computational studies reveal mechanistic details of CO2 adsorption and subsequent conversion to formic acid/formate.

Structure of [co(nh 3 ) 5 Co 3 ]no 3 @bulleth 2 O

— The structure of [Co(NH3)5CO3]NO3•H2O is determined ab initio from conventional X-ray powder diffractometry by the direct methods. The cell is monoclinic, space group P21, Z = 2, a = 7.6733(4) Å, b = 9.6398(5) Å, c = 7.0852(3) Å and β = 106.195(3)°. Refinements by the Rietveld method, lead to RB = 0.053, RP = 0.100, and RWP = 0.119. Hydrogen atoms could not be located. Nevertheless a bonding ...

Collisional dissociation cross sections for O + O 2 , CO andN 2 , O 2 + O 2 , N + N 2 , andN 2 + N 2

Using laboratory data for the scattering of O by O2, CO and N2 pair potentials are constructed for O, C and N atoms. These potentials are then used to calculate collisional dissociation and energy transfer cross sections for O on O2, CO and N2; O2 on O2, N on N2, and N2 on N2. Since the energetic ions often neutralize in the atmosphere corona, such cross sections are relevant to plasma ion bomb...

Electrodeposited Co – Ni – Al O composite coatings 2 3

Composite coatings of Co–Ni–Al O were studied by electrolytic codeposition of Co–Ni alloys and Al O from a sulfamate 2 3 2 3 electrolyte containing Al O particles. The influence of plating parameters on the content of the co-deposited Al O particles in 2 3 2 3 Co–Ni alloys was investigated. The maximum value of co-deposited Al O can be achieved at a particle content of 80 g l in y1 2 3 bath, a ...
