Although glucose electrochemical sensors based on enzymes play a dominant role in market, their stability remains a problem due to the inherent nature of enzymes. Therefore, glucose sensors that are independent on enzymes have attracted more attention for the development of stable detection devices. Here we present an enzyme-free glucose sensor based on Ni(OH)(2) and reduced graphene oxide (rGO). The as-fabricated sensor still exhibits excellent electrocatalytic activity for detecting glucose under enzyme independent conditions. The enhanced catalytic performance may due to synergistic effect as follows: (i) the interaction between the Ni2+ and pi electron of graphene induces the formation of the beta-phase Ni(OH)(2) with higher catalytic activity; (ii) the frozen dry process works as a secondary filtration, getting rid of poorly formed Ni(OH)(2) particles with low catalytic activity; (iii) the rGO network with good conductivity provides a good electronic pathway for promoting electron transfer to reduce the response time. Based on the synergistic effect, the sensor exhibits a wide linear detection range from 0.2 mu mol/L to 1.0 mu mol/L and a low detection limit (0.1 mu mol/L, S/N=3). The excellent detection performance, as well as the easy and low-cost preparation method, suggests the promising applicability of the sensor in the glucose detection market.

The development of sustainable techniques to produce high-performance zeolite is essential to achieve green production in industry. Herein, we report an eco-friendly route to synthesizing hierarchical Beta zeolite from kaolinite and recycled mother liquor. The results reveal that the unutilized species（such as silicon species and Na+） in mother liquor stayed in a stable concentration during eleven recycled experiments. Moreover, the synthesized Beta zeolites still have comparable physicochemical properties and catalytic performance in the esterification of levulinic acid with ethanol over the initial zeolite although eleven recycled experiments. Life cycle assessment exhibits that the synthesis of Beta zeolite with recycled mother liquor can reduce global warming potential by 23% and resource depletion-water use by 36% compared to that without recycled mother liquor. This quantitatively demonstrates that the approach proposed in this work is really a sustainable one, extremely increasing the utilization efficiency of raw materials and decreasing the environmental burden.

FAU型分子筛因其独特的孔道结构已成为化学工业中应用最广泛、用量最大的催化剂、催化剂载体及吸附剂之一.然而,FAU型分子筛单一的微孔孔道限制了客体分子的扩散,导致其性能严重下降.相比之下,等级孔FAU型分子筛具有微-介/大孔复合的多级孔道结构,能够促进大分子的扩散、提高活性位点的可接近性,进而改善其吸附和催化性能.目前,等级孔分子筛的制备方法主要包括“自下而上”的直接合成法和“自上而下”的后处理法.本文主要介绍了近年来等级孔X型和Y型分子筛制备方法的研究现状,重点总结了等级孔X型和Y型分子筛在吸附、催化等过程中的应用性能,并对等级孔FAU型分子筛的绿色化制备进行展望.
