Abstract: A method of making an active catalyst composition includes mixing an alumina support with first catalyst precursor particles and grinding thereby at least partially embedding the first catalyst precursor particles onto surfaces of the alumina support to form a first composite precursor; mixing the first composite precursor and a first solvent to form a first mixture; grinding the first mixture and drying at a temperature of 100 to 150° C.; calcining the first mixture after the drying at a first temperature of at least 200° C. and a second temperature of at least 550° C. thereby allowing the first catalyst precursor particles embedded onto the surfaces of the alumina support to decompose in situ to generate first catalyst particles embedded onto the surfaces of the alumina support and form a first catalyst; and mixing the first catalyst with a second catalyst to form the active catalyst composition.

Abstract: Disclosed in the present invention is an application of a metal sulfide piezoelectric material in piezoelectric catalytic reduction of CO2. The internal electric field generated by the piezoelectric material under external mechanical stimulation pushes electrons and holes to migrate in opposite directions, so that natural advantages are provided for separation and transmission of electron-hole pairs, but there is no report in the prior art that CO2 is reduced into C2+ products by means of piezoelectric catalysis. The present invention provides a metal sulfide piezoelectric nanomaterial and a preparation method therefor. The metal sulfide piezoelectric nanomaterial is used for piezoelectric catalytic reduction of CO2 for the first time, especially piezoelectric catalytic reduction of CO2 to obtain C2+ products so as to broaden the technical route of catalytic reduction of CO2.

Abstract: The present invention relates to a one-dimensional silicate material ZEO-2 with a novel structure and a three-dimensional silicate molecular sieve ZEO-3 obtained by roasting ZEO-2 and a synthesis method therefor and a use thereof. The X-ray powder diffraction characteristics and crystal structures of the two silicate materials are represented. The one-dimensional silicate ZEO-2 can be synthesized by a simple method. The molecular sieve ZEO-3 can be obtained by calcining the one-dimensional silicate ZEO-2 to cause topological condensation. ZEO-2 can be used as a silicon source or a precursor in the synthesis of a novel molecular sieve. The molecular sieve ZEO-3 has good thermal stability and can be used as an adsorbent or a catalyst.
