Renewable energy driven N2 electroreduction with air as nitrogen source holds great promise for realizing scalable green ammonia production. However, relevant out-lab research is still in its infancy. Herein, a novel Sn-based MXene/MAX hybrid with abundant Sn vacancies, Sn@Ti2CTX/Ti2SnC–V, was synthesized by controlled etching Sn@Ti2SnC MAX phase and demonstrated as an efficient electrocatalyst for electrocatalytic N2 reduction. Due to the synergistic effect of MXene/MAX heterostructure, the existence of Sn vacancies and the highly dispersed Sn active sites, the obtained Sn@Ti2CTX/Ti2SnC–V exhibits an optimal NH3 yield of 28.4 µg h−1 mgcat−1 with an excellent FE of 15.57% at − 0.4 V versus reversible hydrogen electrode in 0.1 M Na2SO4, as well as an ultra-long durability. Noticeably, this catalyst represents a satisfactory NH3 yield rate of 10.53 µg h−1 mg−1 in the home-made simulation device, where commercial electrochemical photovoltaic cell was employed as power source, air and ultrapure water as feed stock. The as-proposed strategy represents great potential toward ammonia production in terms of financial cost according to the systematic technical economic analysis. This work is of significance for large-scale green ammonia production.

This study provides a comprehensive overview of the preparation methods for polyhedral oligomeric silsesquioxane (POSS) monomers and polymer/POSS nanocomposites. It focuses on the latest advancements in using POSS to design polymer nanocomposites with reduced dielectric constants. The study emphasizes exploring the potential of POSS, either alone or in combination with other materials, to decrease the dielectric constant and dielectric loss of various polymers, including polyimides, bismaleimide resins, poly(aryl ether)s, polybenzoxazines, benzocyclobutene resins, polyolefins, cyanate ester resins, epoxy resins, and more. Additionally, the research investigates the impact of incorporating POSS on improving the thermal properties, mechanical properties, surface properties, and other aspects of these polymers. The entire study is divided into two parts, discussing systematically the role of POSS in reducing dielectric constants during the preparation of POSS composites using both physical blending and chemical synthesis methods. The goal of this research is to provide valuable strategies for designing a new generation of low dielectric constant materials suitable for large‐scale integrated circuits in the semiconductor materials domain.This article is protected by copyright.

“…Recently, an interesting phenomenon of whisker growth on MAX phases has drawn increasing attention [ 24 , 25 , 26 , 27 , 28 ]. The MAX phases are layered and hexagonal early transition-metal carbides and nitrides, with a general formula of M n+1 AX n (where n = 1, 2, 3; M: early transition metal; A: A-group element; X: C or N) [ 29 , 30 , 31 , 32 ].…”

“…They combine the excellent properties of metals and ceramics, such as good electrical conductivity, high temperature oxidation resistance, and corrosion resistance [ 33 , 34 ]. However, due to the weak bonding between the M 6 X-octahedron layer and the A-atom layer, A-site atoms can be easily released from the lattice points of the MAX phase during mechanical exfoliation [ 24 , 25 , 27 ]. So far, there have been some reports [ 26 , 27 , 28 , 35 , 36 ] confirming that A-site metal whiskers (such as Ga, Sn, and In whiskers) can grow on the corresponding MAX phases (Cr 2 GaC, Ti 2 SnC, and Ti 2 InC, respectively).…”

ZnO whiskers have many applications, such as in medical and photocatalysis fields. In this study, an unconventional preparation approach is reported, realizing the in-situ growth of ZnO whiskers on Ti2ZnC. The weak bonding between the layer of Ti6C-octahedron and the Zn-atom layers leads to the easy extraction of Zn atoms from Ti2ZnC lattice points, resulting in the formation of ZnO whiskers on the Ti2ZnC surface. This is the first time that ZnO whiskers have been found to grow in-situ on Ti2ZnC substrate. Further, this phenomenon is amplified when the size of the Ti2ZnC grains is mechanically reduced by ball-milling, which bodes a promising route to prepare ZnO in-situ on a large scale. Additionally, this finding can also help us better understand the stability of Ti2ZnC and the whiskering mechanism of MAX phases.
