Template-free preparation of layer-stacked hierarchical porous carbons from cheap pitch precursors for high-performance all-solid-state supercapacitors.
Millimeter-sized activated carbon spheres are potential candidates for industrial-scale CO2 capture. sulfur-doped microporous were synthesized from poly(styrene–divinylbenzene), a very cheap and easily operated resin product, in the present work studied uptake. A series of spherical materials yielded through sulfonation, oxidation, carbonization, KOH activation polymer precursors. In addition to promoting cross-linking molecules, sulfonic substituents directly introduced sulfur functional...
Porous carbons represent a typical class of electrode materials for electric double-layer capacitors. However, less attention has been focused on the study capacitive mechanism electrochemically active surface oxygen groups rooted in porous carbons. Herein, degree and variety HNO3-modified samples (N-CS) are finely tailored by mild hydrothermal oxidation (0.0-3.0 mol L-1), while micro-meso-macroporous structures efficiently preserved from original sample. Thus, N-CS is suitable carrier...
Abstract Transition‐metal phosphides (TMPs) with high catalytic activity are widely used in the design of electrodes for water splitting. However, a major challenge is how to achieve trade‐off between and stability TMPs. Herein, novel method synthesizing CoP nanoparticles encapsulated rich‐defect carbon shell (CoP/DCS) developed through self‐assembly modified polycyclic aromatic molecules. The graft removal high‐activity C–N bonds molecules render controllable crystallite defects shell....
Although hierarchitectures could energize carbon materials to address the challenges encountered in emerging flexible energy storage, how make trade-offs among specific surface area, pore configuration, and conductivity is still a lingering issue. Herein, 3D porous assembled by nanosheets (HCAs) with tunable hierarchical structure acquired from amphiphilic coal tar pitch chitosan means of facile microphase separation strategy without any templates. The polar molecular chains surrounding...
A template-free strategy has always been attractive to design and fabricate advanced carbon materials with tunable nanostructures from cheap precursors. Herein, honeycomblike mesoporous carbons (HPCs) are prepared pitch-based polymers through a self-assembly foaming without using any templates. Rich mesopores specific in sizes of 2–5 nm abundant open-ended holes endow hierarchical pore-in-pore feature HPCs an ultrahigh surface area (3473 m2 g–1). With their superior structure, can deliver...
Deep eutectic solvents (DESs) have been intensively investigated as promising green for extraction combined with oxidative desulfurization (EODS) of fuel oil. However, it is still a challenge to explore the effect hydrogen bond acceptor (HBA) and donor (HBD) structure on formation DESs performance desulfurization. In this study, exploratory density functional theory (DFT) calculation was first carried out reveal influence electron HBA preparation DES. Then, structures were optimized, their...
High-entropy oxides (HEOs) are potential electrocatalysts for overcoming the sluggish kinetics of oxygen evolution reaction (OER). Conventionally, thermodynamic barrier lattice mechanism (LOM) is lower than that adsorbate (AEM). However, controlling transition from AEM to LOM remains challenging. Herein, an in situ modulation strategy has been developed synthesize N-FeCoNiAlMoOx by introducing structural directing agents and electronic modulators. Different instruments were used identify...
