Revival of Zeolite‐Templated Nanocarbon Materials: Recent Advances in Energy Storage and Conversion

Abstract

Nanocarbon materials represent one of the hottest topics in physics, chemistry, and materials science. Preparation of nanocarbon materials by zeolite templates has been developing for more than 20 years. In recent years, novel structures and properties of zeolite-templated nanocarbons have been evolving and new applications are emerging in the realm of energy storage and conversion. Here, recent progress of zeolite-templated nanocarbons in advanced synthetic techniques, emerging properties, and novel applications is summarized: i) thanks to the diversity of zeolites, the structures of the corresponding nanocarbons are multitudinous; ii) by various synthetic techniques, novel properties of zeolite-templated nanocarbons can be achieved, such as hierarchical porosity, heteroatom doping, and nanoparticle loading capacity; iii) the applications of zeolite-templated nanocarbons are also evolving from traditional gas/vapor adsorption to advanced energy storage techniques including Li-ion batteries, Li-S batteries, fuel cells, metal-O 2 batteries, etc. Finally, a perspective is provided to forecast the future development of zeolite-templated nanocarbon materials.

Three‐Dimensional Electrodes for Oxygen Electrocatalysis

“…Since zeolites have numertous structural types, the physical properties of the electrode can be easily tuned. [69] Ryoo and co-workers [70] reduced the reaction temperature during hydrocarbon carbonization process by embedding lanthanum ions in zeolites, so that the inside of zeolite templates could freely form carbon structures similar to 3D graphene. An and co-workers [71] prepared N-doped ordered microporous carbon (N-ZTC-4h) by CVD method after silanization by zeolite as template to improve the deposition activity of carbon.…”

Applications of Carbon Nanotubes in the Internet of Things Era

“…Future opportunities in flexible supercapacitors emerge with continuously improving the areal and volumetric capacitance [140], large specific area [141], the handing rate, and the interfaces for coupling various energy nanogenerators. Besides, the CNT-based inks could facilitate the direct printing of supercapacitor electrodes [142].…”

Impact of the crystal size of beta zeolite on the structural quality of zeolite templated carbons

“…The pure ZTCs is achieved after dissolution of the inorganic scaffold classically using concentrated hydrofluoric acid solutions. The important growth in the field of ZTCs can be ascribed to their interesting properties resulting from the combination of tailored micropore topologies and electrical conductivity, 6 which makes them potentially interesting candidates in a number of applications, including electrochemical capacitors, 7 batteries, 8 and hydrogen 9 and methane storage. 10 Different parameters, such as the zeolite framework and the nature of the counterion have been studied in the quest to achieve ZTCs.…”
