Nowadays, charge separation and efficient solar-light absorption are the main challenges in photoreduction of CO2. Although significant efforts have been made to overcome these issues, including use cocatalysts doping, photocatalysts still suffer from low photocatalytic activity stability. Herein, localized surface plasmonic resonance (LSPR) effect Au nanoparticles deposited into zeolitic imidazolate framework (ZIF-67) was investigated for Different loadings ZIF were prepared their effects...
Photocatalytic reduction of CO2 into useful feedstocks has attracted more attention in recent decades. However, the effective and selective conversion to desired product always remains a major challenge photocatalysis, which relies on appropriate band edge potential efficient separation photogenerated charge carriers photocatalysts.

Alkaline earth monoalkoxide free radicals (MORs) have molecular properties conducive to direct laser cooling sub-millikelvin temperatures. Using dispersed induced fluorescence (DLIF) measurements from a pulsed supersonic beam source we determine vibrational branching ratios and Franck-Condon factors for the MORs CaOH CaOCH$_{3}$. With narrow linewidth continuous-wave dye excitation, precisely measure both $\tilde{X}-\tilde{A}$ $\tilde{X}-\tilde{B}$ electronic systems in each molecule. Weak...
The high-pressure melting diagram of iron is a vital ingredient for the geodynamic modeling planetary interiors. Nonetheless, available data molten show an alarming discrepancy.
