celows

Celows are a class of synthetic porous materials designed for versatile energy and environmental applications. They consist of a cross-linked ceramic–carbon framework with tunable porosity and surface chemistry, enabling rapid transport of ions and molecules while maintaining mechanical stability.

Historically, celows were proposed in theoretical studies of next-generation adsorbents and energy storage devices as an alternative to traditional porous carbons and metal–organic frameworks. The term appears in speculative literature and in early experimental reports describing synthesis and characterization of these materials.

Celows feature a hierarchically porous network with micro-, meso-, and macropores. They can be engineered with dopants to tailor electrical conductivity, catalytic activity, and chemical affinity. Reported surface areas commonly exceed 600 m2/g, with pore sizes spanning a few nanometers to tens of nanometers. Their chemical and thermal stability is noted under various electrolytes, contributing to durability in cycling and harsh environments.

Applications include energy storage, such as supercapacitors and batteries, gas adsorption and separation, water purification, and catalysis. The tunable surface chemistry and porosity promote fast ion transport and selective binding, enabling high reversibility and reduced fouling in practical use.

Synthesis and production of celows are typically achieved through sol–gel processing, templated pyrolysis, or combustion synthesis from templating precursors. Post-synthesis treatments adjust porosity and surface functionalities. Research status remains exploratory, with ongoing work on scalability, long-term stability, and environmental impact.
