MOF-based heterojunctions can significantly enhance the efficiency of photocatalytic hydrogen production; however, construction efficient remains a formidable challenge. In this study, we successfully developed series Type II by growing TiO2 on Cr-based MOF, thereby regulating generation, separation, and transportation photogenerated charge carriers to improve evolution performance. Among these, 23%TiO2/MIL-101(Cr) photocatalyst exhibited highest production activity, achieving 884.01 μmol g–1 in just 5 h, which is 6.8 6.0 times that pure MIL-101(Cr) TiO2, respectively. Additionally, demonstrated excellent cyclic stability. Tiny particles were proven mainly deposited surface N2 sorption isotherm analyses, transmission electron microscopy (TEM), high-resolution TEM, high-angle annular dark field scanning microscopy, etc. Characterization techniques such as situ XPS confirmed formation TiO2/MIL-101(Cr) heterostructure. Band structure analysis indicates meets thermodynamic requirements for production. Furthermore, transient photocurrent measurements, electrochemical impedance analysis, photoluminescence reveal possesses superior capabilities carrier transport, resulting from kinetic perspective. This research offers valuable insights into preparation development photocatalysts

ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.

Electrocatalytic nitrogen reduction reaction (NRR) has attracted much attention as a sustainable ammonia production technology, but it needs further exploration due to its slow kinetics and the existence of competitive side reactions. In this research, xAu/MIL-101(Fe) catalysts were obtained by loading gold nanoparticles (Au NPs) onto MIL-101(Fe) using one-step strategy. Herein, MIL-101(Fe), with high specific surface area strong N

While photocatalytic CO2 reduction has been intensively investigated, reports on the influence of anions coordinated to catalytic metal sites photoreduction remain limited. Herein, different (F–, Cl–, OAc–, and NO3–) around single Co installed bipyridine-based three-component covalent organic frameworks (COFs) were synthesized, affording TBD-COF-Co-X (X = F, Cl, OAc, NO3), for reduction. Notably, presence these significantly influences performance, where TBD-COF-Co-F exhibits superior activity its counterparts. Combined experimental theoretical results indicate that enhanced in is attributed efficient charge transfer, high adsorption capacity, low energy barrier activation. This study provides a new strategy boosting COF photocatalysis through anion regulation sites.
