Accepted: 24 August 2020
The most common method for preparation of catalytically active free-standing hybrid material (CAFH) is that supporting material is formed and subsequent catalytic agent deposited on its surface. But it remains challenging to agilely prepare CAFH with different shape and size. We employ a facile process combined with defect-induced electroless nickel plating and selective laser sintering (SLS) forming to fabricate CAFH. Results manifested CH3COOHetched treatment resulted in the formation of defect (amorphous structure, amide group and hole) on the Nylon 12 (PA12) surface, which would induce electroless Ni plating. The mechanism of the electroless plating is the destruction of the structure of [C6H5O73--Ni] ligand around defect; subsequently, the reduction of the REDOX barrier. The following laser sintering of the plated PA12 powder could fabricate CAFH with an irregular network. There are two stages during the SLS process: balling of particle and formation of sintered neck. The combination of the structural stability, high surface area and recyclability gives a CAFH with demonstrated catalytic property. CAFH is agile to prepare, easy for quick-to-assemble material and realizable in CAFH shape design. The new technology possesses vast exploration and application value.

1 Introduction With the booming development of energy technology and advanced material in recent years [1–4], catalytic material is garnering more and more attention. A wide range of micro-nanometal and oxide particles have been reported so far as effective catalytic agents [3–7]. It is commonly known that the characteristics of catalytic material, such as composition, dispersion, structural and interface properties would greatly influence its catalytic capability [4–7]. The catalytic agent tends to aggregate due to their high surface energy, and then the catalytic capability is decreas
