Hierarchical Sn-Beta was prepared by a hydrothermal postsynthesis method. It shows higher catalytic activity for conversion of glucose to alkyl lactate than microporous Sn-Beta hydrothermally synthesized in fluoride media.

The electroproduction of H2O2 through 2e oxygen reduction reaction (ORR), as an alternative strategy for the conventional anthraquinone process, is highly energy-efficient and environmental-friendly. Different kinds of electrocatalysts with high...

A new noncentrosymmetric mixed-alkaline borate, Li 2 CsB 7 O 10 (OH) 4 (1), was made under solvothermal conditions. This layered boron oxide framework consists of unique bird-shaped [B 7 O 12 (OH) 4 ] 7− clusters with large 14-ring pores. Its second-harmonic-generation (SHG) signal is 2.5KDP (KH 2 PO 4 ), with its short ultraviolet (UV) cutoff edge indicating that this crystal is a potential deep-UV transparent nonlinear-optical material.

Under solvothermal conditions, a chair open-framework borate, NaBO(HO)(HO) (1), has been synthesized. Compound 1 shows regular pores of zeolites as well as nonlinear optical (NLO) properties of borates. The large 13-ring channels of the boron oxide framework are constructed from different cluster units of BO and BO with three-ring units. The second harmonic generation (SHG) signal intensity of 1 is similar to that of KHPO (KDP) and gradually increased with larger particle size. Compound 1 is a potential UV NLO material for its short wavelength absorption edge.
