Nanoconfinement engineering for enchanced adsorption of carbon materials, metal–organic frameworks, mesoporous silica, MXenes and porous organic polymers: a review

Recent Development in Nanoconfined Hydrides for Energy Storage

“…Metal-organic frameworks (MOFs) have recently been utilized as hosts for metal hydrides, due to their tunable porosity, stability and enhancement of kinetic and thermodynamic properties of hydrogen storage materials (Table 3). Their functionalization with appropriate groups/molecules opens new doors in energy storage field, being able to bypass side-reactions, alter significantly the reaction pathway, and afford a better reversible material in hydrogen release/uptake studies [39,40,68,86,[147][148][149][150][151][152][153][154][155][156][157].…”

“…Attempts to restrict oxygen and moisture exposure of active hydrogenation sites in hydride materials have been made through the engineered approach of covering the hydride materials with a layer of H 2 -permeable polymer [88,127,156,[173][174][175]. This approach proved to be very successful, provided that the hydride coverage was indeed complete (Table 6).…”

“…Ongoing recent trends in developing novel systems for energy storage have incorporated MXene materials with a 2D structure, as promising hydride hosts [94,156,[176][177][178][179][180][181][182][183][184][185][186][187][188][189][190][191][192][193][194]. While only few examples are currently available, it is foreseeable that MXenes will grow to become a mainstream storage matrix for nanoconfined hydride-based materials (Table 7).…”

Few-layer graphitic carbon nitride for enhanced visible-light photocatalytic efficiency: the role of narrow bandgap and nitrogen-vacancies

“…Various reports also highlighted that the template-assisted synthesis strategy is a controllable and promising method for the fabrication of desired structures and functionalities. 27,29,30 Inspired by these research studies, we fabricated the fewlayer g-C 3 N 4 nanosheet by using RUB-15 as the confined template and investigated the photocatalytic activities. The template RUB-15 is a kind of layered silicate 31,32 which is composed of silicate layers with a structure similar to that of sodalite and interlayer tetramethylammonium (TMA + ) ions.…”
