ABSTRACT
Accepted: 6 September 2020
One of the main challenges in the field of heterogeneous catalysis is the involvement of thin solid films and membranes and their application in flow systems. In this regard, we report here the application of self-supported bacterial cellulose (BC) reinforced nanosized platinum (Pt)/N-doped bamboo-like carbon nanotube (NBCNT) hybrid catalyst membrane with a thickness of 35 ± 5 lm in the hydrogenation of n-butene. To synthetized the BC-NBCNT/Pt nanohybrid membrane catalyst a simple impregnation route was applied in a two-step process. As-prepared material was tested in a continuous flow system and the conversion was followed directly by using Fourier transform infrared spectroscopy. Furthermore, the fabricated films were characterized by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and specific surface area measurement (Brunauer–Emmett–Teller). Hydrogenation performance was studied on both single and double films. Results revealed that 97% conversion of n-butene can be achieved using these bacterial cellulose reinforced hybrid membranes.

GRAPHIC ABSTRACT
Introduction There has been growing interest over the last decade in the involvement of hybrid materials in the field of catalysis, due to advantages such as high specific surface area, simplicity of operation or high material conversion efficiency [1]. As the expectations for hybrid and composite structures are increasing continuously, research is focusing on the design of catalysts combining nanomaterials and metallic particles. Among transition metals, platinum (Pt) and Ptbased materials are regarded as highly active and effective catalysts [2]. It is well known that nanosized Pt has one of the highest catalytic activity levels in chemical reactions [3] and catalytic hydrogenation [4] due to its high active surface area [5]. Consequently, Pt-based catalysts should be ultrafine powders containing Pt particles in the nanometre range to offer a large number of active sites and a large surface area. However, the work with ultrafine powd
