Dalam laporan ini, SnO2 didopkan cerium telah disintesis dengan menggunakan kaedah pengisitepuan . SnO2 komersial, cerium (III) nitrat hexahydrate (Ce (NO3)3.6H2O) dan etanol dicampurkan pada suhu bilik dan seterusnya diikuti dengan proses pengkalsinan. Serbuk pemangkin telah disintesis dengan mengubah komposisi cerium (III) nitrat hexahydrate. Produk berkenaan telah dicirikan dengan menggunakan kaedah analisis X-ray Diffraction (XRD), Brunauer - Emmett -Teller (BET), Scanning Electron Microscopy (SEM) dan Energy Dispersion X-ray (EDX). Serbuk pemangkin telah dipeletkan dan diujikan prestasi pemangkinannya dalam reaktor berskala kecil. Penukaran ethanol diubah dengan suhu operasi yang berbeza , masa yang diambil untuk etanol untuk bertindak balas dan kepekatan etanol masuk ke dalam reaktor. Hasil kajian menunjukkan bahawa SnO2 didopkan 20 wt % Ce mempamerkan penukaran etanol tinggi dan menunjukkan potensi tinggi sebagai sensor untuk mengesan etanol.

In this report, Cerium doped SnO2 was synthesized by using impregnation method. Commercial SnO2 as a base, cerium (III) nitrate hexahydrate (Ce(NO3)3.6H2O) as a solute and ethanol as a solvent were mixed at room temperature combined and followed by a subsequent calcination process. The catalytic powder was synthesized by varying the composition of cerium (III) nitrate hexahydrate. The products were characterized by X-ray Diffraction analysis (XRD), Brunauer-Emmett-Teller (BET), Scanning electron microscopy (SEM) and Energy Dispersive X-ray (EDX). The catalytic powder was pelletized and tested the catalytic performance in a small scale packed bed reactor. The ethanol conversion was varied with different operating temperature, time take for ethanol to react and inlet ethanol concentration. The result showed that the 20 wt% Ce doped SnO2 exhibited high ethanol conversion, implying the potential application of the sensor for detecting ethanol.
