“…Much research has confirmed that GN could serve as an ideal substrate for the deposition of inorganic nanoparticles. [34] The reasons why the TiO 2 -RGO nanocomposites may enhance catalytic activity are as follow. Firstly, due to its two-dimensional π-conjugation structure, RGO can act as an electron acceptor, and electros could be quickly transferred from the conduction band of TiO 2 to RGO, thus forming electron −hole pairs, which yields an enhanced photocatalytic activity of the composites.…”

In this work, the NiFe2O4@TiO2/reduced graphene oxide (RGO) ternary nanocomposites with high saturation magnetization and catalytic efficiency have been synthesized through the following steps. First, graphene oxide was prepared using the modified Hummer's method. Second, the NiFe2O4 nanoparticles were successfully prepared using the hydrothermal method. Third, the core shell‐structured NiFe2O4@TiO2/RGO nanocomposite precursors were easily obtained through hydrolysis reaction. The morphology of NiFe2O4@TiO2/RGO nanocomposites was characterized from scanning electron microscope (SEM) and transmission electron microscope (TEM) images. Moreover, the results of X‐ray diffraction (XRD) patterns proved that the TiO2 coating shell consisted of anatase. The vibrating sample magnetometer (VSM) measurements showed that the saturation magnetization value of NiFe2O4@TiO2/RGO ternary nanocomposites was 25 emu/g. The X‐ray photoelectron spectroscopy (XPS) analysis confirmed that only part of the graphite oxide (GO) was reduced to RGO in the ternary nanocomposite. The degradation experiments proved that NiFe2O4@TiO2/RGO nanocomposite exhibited the high catalytic efficiency and outstanding recyclable performance for rhodamine B (RhB).

“…Due to unique advantages like high surface area, adjustable nanoscale porosity, nontoxicity, and excellent structural and mechanical stability, great amounts of nanostructured porous carbon materials have found important applications in catalysis, absorption, separation, gas sensing, biotechnology, and energy storage and conversion. [1][2][3][4][5] With particular promise in innovatively solving the problems of global energy consumption and environmental pollution, considerable endeavours have been dedicated to enhance the performance of porous carbon-based energy storage devices in recent years. [6,7] In these energy models, supercapacitors (SCs) including two major types (electrical double layer capacitor (EDLC) and pseudocapacitor) show the prominent potential in substituting or complementing batteries as they can achieve high power density and long cycle life.…”

The pursuit of promising precursors and simple preparation approaches boosts the development of sustainable carbon‐related energy systems. In this work, a relatively low‐cost and eco‐friendly ternary precursor system is presented for the fabrication of interconnected sheet‐structured porous carbon materials by the combination of template‐assisted pyrolysis and post‐activation. The variation of effect factors permitted the formation of tunable microstructures with multilevel pore channels, and the optimized sample (APC3‐700) with multiple desired properties (such as, large surface area, hierarchical interconnected pores, and nitrogen doping) was successfully synthesized. Due to the large electrode/electrolyte interface, short pathway for mass/charge transfer, high electrochemical activity, and low transport resistance, APC3‐700 proved to be a favorable material with high capacitance (225 F g−1 at 1 A g−1) and a high rate profile (remaining 91 % at 20 A g−1). In particular, the symmetrical supercapacitor assembled demonstrated a long cycle life with almost no capacitance decaying over 20 000 cycles. The method used may be employed for the widespread development of nanosheet‐connected carbon materials from different sources for efficient enhancement of energy storage.

A new rapid and efficient approach is developed for the preparation of porous materials via cationic polymerization of octavinylsilsesquioxane (OVS). The reaction proceeds rapidly and efficiently at room temperature, forming a predominantly covalent porous network polymer. A series of experiments are conducted to clarify the effects of reaction time, temperature, and solvent on the polymerization process. The results show that all the products possess a nanoporous structure with surface areas of approximately 300 – 620 m2 g−1 and a pore volume of 0.15 – 0.54 cm3 g−1. The porosity of these polymers can be readily tailored by changing the reaction conditions. The post functionalization of the materials is further investigated by epoxidation and the application of these polymers as carbon dioxide adsorbents (up to 0.98 mmol g−1) is also explored. The work has general implications in understanding the reactive nature of the cationic polymerization of OVS and is very promising for promoting the application of porous materials.
