In search of optimal structures for functional materials fabrication, the gyroid (G) structure has emerged as a promising subject of widespread research due to its distinct symmetry, 3D interconnected networks, and inherent chiral helices. In the past two decades, researchers have made great progress fabricating G-structured functional materials (GSFMs) based on G templates discovered both in nature and in the lab. The GSFMs demonstrate extraordinary resonance when interacting with light and matter. The superior properties of GSFMs can be divided into two categories based on the dominant structural properties, namely, dramatic optical performances dominated by short-range symmetry and well-defined texture, and effective matter transport due to long-range 3D interconnections and high integrity. In this review, G templates suitable for fabrication of GSFMs are summarized and classified. State-of-the-art optical applications of GSFMs, including photonic bandgap materials, chiral devices, plasmonic materials, and matamaterials, are systematically discussed. Applications of GSFMs involved in effective electron transport and mass transport, including electronic devices, ultrafiltration, and catalysis, are highlighted. Existing challenges that may hinder the final application of GSFMS together with possible solutions are also presented.

“…Ammonia desorption prole for Beta zeolite indicates on the presence of weak, medium and strong acidity, which is compatible with results revealed elsewhere. 29,50 High concentration of weak and moderate acidic sites on Beta, which prevents over cracking of products and reactants, is the reason of higher selectivity of this zeolite to intermediate cracking products in heavy oil upgrading. 30 CLT sample has also three distinct peaks at 126 C, 337 C and 654 C. It has been proposed that high temperature peak is associated to the framework Al atoms which induce strong acidity, while low temperature peak represents weak acid sites ascribed to nonframework Al atoms.…”

“…24,25 Different composites of zeolite beta have been synthesized for different intentions, for example it has been used in beta/Y composite in order to benet from larger pore openings of beta zeolite coupled with high acidity of Y zeolite, 26,27 or in beta/MCM-41 composite to induce larger mesopore volume attained from mesoporous structure of MCM-41 aluminosilicate paired with moderate acidity of zeolite beta. [28][29][30] Therefore, beta zeolite has potential to be paired with different kinds of zeolites in a composite.…”

“…The strong broaden peak near 1090 cm attributable to Si-O-Si bending vibration and symmetric stretching vibrations. Two bands centered at ~520 and 570 cm-1 are typical vibration modes for zeolite Beta (six-or five membered rings of T-O-T(T=Si or Al) in micro porous zeolites) [38]. Similar to the SiO2-based mesoporous materials MCM-41, the framework vibration spectrum of BM (40) consists of bands centered at ~461, 800, and 1090cm -1 .…”

Abstract. Micro-mesoporous composite material Beta-MCM-41(BM) were hydrothermally synthesized by treating parent beta with molar SiO 2 /Al 2 O 3 ratios of 12.5, 20 and 30 as precursors. The influence of SiO 2 /Al 2 O 3 ratio of zeolite beta on effective micro-mesoporous composite formation was studied by investigating the crystallinity, morphology, chemical composition, acidity and textural property of Beta-MCM-41 through XRD, nitrogen adsorption, SEM, TEM, NH 3 -TPD, FTIR and Pyridine-FTIR. The catalytic performance was evaluated in terms of n-heptane hydro isomerization. The results demonstrated that Beta-MCM-41 supported Pt catalysts showed higher selectivity to isoheptanes than Pt/Beta. It was attributed to the superiorities of the pore structure and mesoporous accelerated the diffusion of larger molecules of isoheptanes.
