Under a low applied heat flux of 30 kW/m 2, for every 1g of pyrolysis, another 0.6g of additional mass loss is incurred due to the presence of char oxidation. WebThe conductivity change in the TiO 2 component can be correlated with the action of activated hydrogen species formed on platinum and having diffused onto the titania support in a spillover form. The spilt-over hydrogen species can be described as surface electron donors, i.e. as coexisting H atoms and H + ions. smart led lights walmart
