The significantly improving of TMM hydrothermal stability was due to increase the surface hydrophobicity and the ratio of T12-ring, and decreased remarkably number of hydrophilic silanol groups. After hydrothermal treatment for 17-day, TMM also exhibited more efficient catalytic activation than MCM-41 ...
Additionally, the study explores the design and implementation of artificial chloroplasts, focusing on the efficacy of light reactions in water splitting and electron transfer processes. Overall, this review contributes to the expanding knowledge of greenhouse gas regulation and photosynthesis optimization. ...

Determine the number of electron groups, the electron geometry, and the molecular shape. Is it polar or nonpolar? Draw the Lewis structure for NH4+. Determine the number of electron groups, the electron geometry, and the molecular shape. Is it pol...
The morphology and thickness of the membranes were investigated using a scanning electron microscope (SEM, FEI Magellan 400 field emission XHR-SEM) operated at an accelerating voltage of 3 kV and a probe current of 6.3 pA. No conductive coating was applied to the samples. The membranes were mo...
Due to the large number of possible products and their similar reduction potentials, a significant challenge in CO2 photoreduction is achieving selectivity to a single product while maintaining high conversion efficiency. Controlling the reaction interme
Plenty of research reported that a ppm grade of H2S would suppress the activity of iron-group metals in hydrogasification because the electron in sulfur will strongly absorb in the empty d-orbit of Co and Ni, which restrained the disassociation of H2 and the activation of carbon structure by ...
bElectron selectivity (Selelectron) of CH4: Selelectron(%) = (8 v(CH4))/(8 v(CH4) + 2 v(CO) + 2 v(H2) + 2 v(HCOOH)) × 100%; cProduct selectivity (Selproduct) of CH4: Selproduct(%) = (v(CH4))/(v(CH4) + v(CO) + v...
Along the microreactor, the total volumetric flow rate increases because the reforming reaction increases the number of moles in the gas mixture. The actual residence time is therefore different from the space time τ defined by the following: 𝜏=𝑉/𝑄τ=V/Q (8) where 𝑉V (m3) is...
The Langmuir adsorption equation is: θ = 1 KP + KP (2) where "θ" is the number of sites of the surface which are covered with gaseous molecules, K is the associated equilibrium constant (a thermodynamic quantity) and P is the pressure. The Freundlich adsorption equation is: x m = ...
