Thereafter, TiO(OH)+ combined with HCO3− to form water and CO2, and OH− reacted with HCO3− to form water and CO32− (Eqs. 7-(9). Hence, the addition of TiO2 had changed the regeneration pathways, since the formed transition state TiO(OH)+ and OH− had accelerated HCO3...

It is proposed that in the pyrolysis CO2 can not only react with VOCs to generate CO as an oxygen donor, but also expedite the pyrolysis of VOCs. The water-gas-shift reaction (Eq. (11)) has also been used in the biomass pyrolysis. In the example of orange peel pyrolysis, an ...
whereas Co single atoms trap holes and catalyze water oxidation. More importantly, the maximum electron transfer efficiency for CO2photoreduction, as measured with in-situ μs-transient absorption spectroscopy, is found to be 35.3%, owing to the combined effect of the ionic liquid and Co single ...
Compared with the photoreduction of CO2 on Bi in H2 gas, the CO2 conversion on Bi-Hx avoids the unfavorable H2 dissociation step, and the stored H might directly react with CO2. To further understand the role of the stored hydrogen in the CO2 reduction process, we calculated the free ...

The complex 2 was air-stable and unreactive towards water, methanol, and other substrates (e.g., nitriles) at room temperature over 24h but reacted with CO2 (ca. 1atm) to generate [Zn3(μ-H)2(μ-1,1-O2CH)] (3). In contrast, [Zn3(OH)3L] (4) was found to be unreactive ...
(2015). The model calculates change in fracture permeability as a consequence of diffusion and dispersion when CO2-saturated water reacts with cement. The authors conducted 250 simulations with aperture width ranging from 6 to 90 μm, initial flow rates from 0.0015 to 0.130 ml/min, and ...
