Abstract: A high-surface-area, highly porous manganese oxide (MnOx) in the form of xerogel or aerogel monoliths or powders comprising a manganese oxide nanoarchitecture comprising an interior surface area >200 m2 g?1, wherein the MnOx gel has a void structure comprising pores that are sized from 2-150 nm, and wherein the manganese oxide nanoarchitecture removes toxic gas from a toxic gas and air mixture at room temperature via an oxidative mechanism that converts the toxic gas to an innocuous adsorbed substance. These high-surface-area, ultraporous manganese oxide (MnOx) xerogels and aerogels exhibit outstanding filtration performance for multiple, chemically distinct toxic gases, including ammonia, sulfur dioxide and hydrogen sulfide. These MnOx materials use multiple mechanisms for small molecule capture/catalysis including molecular sieving and oxidative decomposition, and function in a wide range of humidity conditions.

Abstract: This disclosure describes the first viable non-enzyme protein encapsulated within an aerogel. In this, a large excess of cyt c is added to a commercial buffered Au sol solution ( ) which results in the formation of a gold˜protein-protein superstructure in the absence of separation techniques which destroy the superstructure. The gold˜protein-protein superstructure is then nanoglued into a silica framework during the sol to gel transition. To form the gel, the Au˜cyt. c superstructure in buffered medium is added to a silica sol and the composite gels are washed with acetone followed by liquid carbon dioxide and then supercritically dried to form the aerogel. The biocomposite aerogels have a multiplicity of applications particularly in the realm of sensing and energy transformation.
