In this work, we have introduced piperidine cations into conventional carbonate electrolytes to induce the generation of a graded, high mechanical modulus solid electrolyte surface (SEI). This multilayer graded structure of SEI, with inorganic material inside and organic material outside, protects the hard carbon electrode during cycling and enhances the rate performance of the hard carbon electrode in organocarbonate electrolytes. At the end of the cycle, a “pseudo-SEI” structure with an ordered graphite structure was observed on the surface of the hard carbon electrode in the modified electrolyte.

In the present study, the incorporation of Ru into the framework of ZIF-8 resulted in that the Ru-ZIF-8 nanozyme with both esterase-like activity and peroxidase-like activity. Owing to the dual nanozymatic activities of Ru-ZIF-8 nanozyme, the acetylcholine (ACh) detection process utilized only one natural enzyme (choline oxidase), which greatly simplified the detection procedure. In the detection process, nanozyme Ru-ZIF-8 showed esterase-like activity to catalyze the hydrolysis of ACh to choline. Then the generated was oxidized by choline oxidase to generate H2O2. Finally, Ru-ZIF-8 with peroxidase-like activity was used to catalyze H2O2 to oxidize 2,2'-azino-bis (3-ethylbenzothiazo-line-6-sulfonic acid) ammonium salt with the color change. As a result, the linear range for ACh was from 0.01 μM-22 μM with the detection limit (DL) of 5.5 nM. In addition, Ru-ZIF-8 was utilized to fabricate a portable detection test strip. Our work provided a simple, portable, low-cost, highly sensitive and selective assay for the detection of ACh, which paved the way for the development of multi enzyme cascade assays.

2D CoNi-BDC ultrathin nanosheets (N-CoNi-BDC) were synthesized from a mixed solution of benzenedicarboxylic acid, Ni2+, and Co2+ through a simple ultrasonic treatment. CoNi-BDC with an irregular bulk morphology (B-CoNi-BDC) was produced when the aforementioned mixed solution was aged without ultrasonic treatment. The N-CoNi-BDC possessed an improved electrochemical performances because of having a more exposed pore structure and higher specific surface area, both of which are important for electrolyte infiltration and ion/electron transport.
