Effect of temperature of oxalic acid on the fabrication of Porous anodic alumina from Al-Mn alloys
Mohd Nazree, Derman, Dr.; Foo, Kai Loong; Khairel Rafezi, Ahmad, Dr.; Uda, Hashim, Prof. Dr.; Voon, Chun Hong (Hindawi Publishing Corporation, 2013)The influence of temperature of oxalic acid on the formation of well-ordered porous anodic alumina on Al-0.5 wt% Mn alloys was studied. Porous anodic alumina has been produced on Al-0.5 wt% Mn substrate by single-step ... -
Electrochemical measurement of PBS using cyclic voltammetry and AAO fabricated at ambient temperature and low potential
Alaba Oladeji, Araoyinbo; Mohd Nazree, Derman, Dr.; Azmi, Rahmat, Prof.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2013)Anodic aluminium oxide fabricated at ambient temperature and low potential in phosphoric acid electrolyte was used as the working electrode for the electrochemical measurement of phosphate buffer saline under different pH ... -
Organic dye degradation with TiO2 catalyst/AAO template in the presence of H2O2
Alaba Oladeji, Araoyinbo; Mohd Nazree, Derman, Dr.; Azmi, Rahmat, Prof.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2013)In this study, anodic aluminum oxide (AAO) fabricated from phosphoric acid electrolyte at ambient temperature was used as the porous template, while a sol gel procedure was used for the preparation of the TiO2 sol with the ... -
Room temperature anodization of aluminum and the effect of the electrochemical cell in the formation of porous alumina films from acid and alkaline electrolytes
Alaba Oladeji, Araoyinbo; Azmi, Rahmat, Assoc. Prof. Dr.; Mohd Nazree, Derman, Dr.; Khairel Rafezi, Ahmad, Dr (VBRI Press, 2012)Nanoporous alumina was produced by anodic oxidation of aluminum in both acidic and alkaline electrolytes. Previous reports indicate that nanoporous aluminais mainly produced from strongly acidic electrolytes, and with the ... -
A simple one-step anodising method for the synthesis of ordered porous anodic alumina
Voon, Chun Hong; Mohd Nazree, Derman, Dr.; Uda, Hashim, Prof. Dr.; Khairel Rafezi Ahmad, Dr.; Ho, Li Ngee (Taylor & Francis, 2014)Porous anodic alumina (PAA) has been produced on aluminium substrate by single-step anodising at 50 V in 0.3 M oxalic acid at 15°C for 60 min. The highly ordered pore and cell structure was achieved by subjecting the PAA ... -
Using gibbs standard state free energy and a power regulating device to predict and control the fabrication of nanoporous alumina
Alaba Oladeji, Araoyinbo; Azmi, Rahmat, Prof.; Mohd Nazree, Derman, Dr.; Khairel Rafezi, Ahmad, Dr. (VBRI press, 2013-12)The basic concept of Gibbs standard state free energy predicts a favorable condition for both room and high temperature fabrication of nanoporous alumina in phosphoric acid electrolyte. The anodization of aluminum foil in ...
