A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves longer hydrocarbon chains over shorter hydrocarbon chains. The nanoparticles exhibit an edge to facet ratio to provide for more interactions with the facets.

Disclosed herein are catalysts and methods of making and use thereof, wherein the catalysts comprises a layered inter-metallic compound.

The present disclosure provides a noble metal-transition metal-based nano-catalyst thin film and a preparation method thereof, belonging to the fields of energy development and pollutant emission reduction. Based on a micro-nano processing technology, a noble metal-transition metal-based nano-catalyst thin film is loaded on a semi-cylindrical pipe with an inner thread structure, and heat generated is quickly accumulated on an upper surface of the catalyst to establish a large temperature gradient. By the insulation and high roughness of an alumina carrier layer and the inner thread structure of the pipe, a catalyst loading area is maximized and dispersion of noble metal atoms is enhanced. A transition metal-transition metal oxide thin film protects a noble metal nano-catalyst by core-shell wrapping, and a transition metal oxide prevents catalyst deactivation caused by oxygen occupying too many metal active sites.

A method of providing a particulate material from an at least substantially metallic and/or ceramic starting material, comprising the following steps: (a) generating the particulate material from the starting material by vaporizing the starting material by introducing energy, preferably radiation energy, in particular by means of at least one laser, into the starting material and subsequently at least partially condensing the vaporized starting material, b) collecting the particulate material in at least one receiving and/or transporting device, in particular at least one container, c) receiving, in particular storing, and/or transporting the particulate material in the receiving and/or transporting device and/or in a further receiving and/or transporting device such that it can be used for a subsequent process, in particular in a state of at least non-permanent passivation, and d) providing the particulate material for the subsequent process.
