High Pore Volume Mesoporous Carbon (UVMC11) for Supercapacitor and Catalyst Support, 5 g/bottle, CSCSHPVMC

High Pore Volume Mesoporous Carbon (HPVMC) is a critical class of material for next-generation energy storage, particularly as a scaffold for loading pseudocapacitive or electrocatalytic "guests." When the pore volume exceeds 1.5-2.0 cm3/g, the carbon transitions from a simple surface-area provider to a high-capacity "host" that prevents guest materials from clumping or clogging.

In supercapacitors, "High Surface Area" (SSA) is often the focus, but Pore Volume is the metric that dictates how the device handles high power and mass loading: (1) Ion Reservoirs: High pore volume allows the material to act as an "electrolyte tank." This ensures that even during rapid discharge (high power), there is a local supply of ions ready to form the double layer, preventing "ion depletion" within the electrode. (2) Loading Capacity: If you are adding a pseudocapacitive catalyst (like MnO2, Ni(OH)2, or conductive polymers), high pore volume is required to hold these heavy materials without sealing the pores. A low-volume carbon will become "blinded" once the catalyst is added, leading to a massive drop in ion accessibility. (3) Massive Triple-Phase Boundary: In gas-evolving or gas-consuming reactions, the high void space allows for simultaneous transport of electrons (through the carbon), ions (through the electrolyte), and gas bubbles (out through the macroporous/mesoporous channels).

When used to support metal oxides or noble metals (like the IrRuOx or AgNPs discussed earlier), HPVMC provides several structural benefits: (1) Nano-confinement: Particles are trapped in individual mesopores, which prevents sintering (particles clumping together) over time. (2) Conductive Scaffold: It provides a 3D network of sp2 hybridized carbon and enhances the performance of semi-conductive oxides like MnO2.

Notes: Please try to store the high pore volume mesoporous carbon powder in a dry place.
