Two new Cu-based borate catalysts with cubic supramolecular cages for efficient catalytic hydrogen evolution

Abstract

Two new copper-based borates with supramolecular cages were synthesized under hydrothermal condition. As new copper complexes, they exhibit photocatalytic activity. The experimental results show borates have potential applications as water reduction catalysts (WRCs).

Structural Characterization and ORR Activity of a Copper Complex Borate and an Unexpected [Ni(atta)(SO4)0.5]+ Borate-Sulfate

“…In addition, borate catalysts have been developed rapidly, which has attracted worldwide concerns of chemists, due to their environmental protection characteristics, high abundance, and low cost. Jia et al investigated the photocatalytic activity of Cu-based borates . With the participation of photosensitizers and sacrificial electron donors, Cu-based borates were used as photocatalytic water-reduction catalysts.…”

Three Inorganic–Organic Hybrid Gallo-/Alumino-Borates with Porous-Layered Structures Containing [MB4O10(OH)] (M = Al/Ga) Cluster Units

“…Crystalline borates are promising materials because of their structural diversities and potential applications in nonlinear optical fields. − Boron atoms mainly adopt two coordination modes of BO 3 triangles and BO 4 tetrahedra. These two units can form different oxoboron clusters with different shapes and sizes, which can act as secondary building units to construct different structures of isolated clusters, 1D chains, 2D sheets, and 3D frameworks .…”

Tailoring Hybrid Aluminoborate Frameworks by Incorporating Multicomponent Cadmium–Amine Complexes with Various Conformations

“…Boron-oxo clusters, an anionic, molecular sub-family of boron oxides, have attracted considerable attention owing to their specific roles in the construction of advanced borate crystal materials with exceptional nonlinear optical (NLO) applications, represented by the typical BBO, LBO, KBBF, and CLBO . These clusters are built up by the interlinkage of BO 3 triangles and/or BO 4 tetrahedra through corner-sharing O atoms, featuring various architectures with variable B/O ratios. − An effective strategy for enriching the structural multiformity is to integrate bridging metal ions (e.g., Al, Ga, Mg, and Cu) with different coordination fashions to assemble these boron-oxo clusters into novel metal borates. − Aluminum emerged as a good candidate as it adopts flexible coordination geometries, including tetrahedral AlO 4 , trigonal-bipyramidal/square-pyramidal AlO 5 , and octahedral AlO 6 , and thus, it can interact with the neighboring {B x O y } clusters in a variety of linkage modes to construct aluminoborate frameworks with an intersecting channel system and diversified topologies. − In addition, the chiral AlO 4 centers could deliver their chirality to boron-oxo clusters, thus leading to a noncentrosymmetric inorganic Al–B–O backbone, which promisingly promotes the NLO performance of materials.…”
