Photoelectrocatalysis: Fundamentals and Applications presents an in-depth review of the topic for students and researchersworking on photoelectrocatalysis-related subjects from pure chemistry to materials and environmental chemistry inorder to propose applications and new perspectives. The main advantage of a photoelectrocatalytic process is the mildexperimental conditions under which the reactions are carried out, which are often possible at atmospheric pressure androom temperature using cheap and nontoxic solvents (e.g., water), oxidants (e.g., O2 from the air), catalytic materials (e.g.,TiO2 on Ti layer), and the potential exploitation of solar light. This book presents the fundamentals and the applications of photoelectrocatalysis, such as hydrogen production fromwater splitting, the remediation of harmful compounds, and CO2 reduction. Photoelectrocatalytic reactors and lightsources, in addition to kinetic aspects, are presented along with an exploration of the relationship between photocatalysisand electrocatalysis. In addition, photocorrosion issues and the application of selective photoelectrocatalytic organictransformations, which is now a growing field of research, are also reported. Finally, the advantages/disadvantages andfuture perspectives of photoelectrocatalysis are highlighted through the possibility of working at a pilot/industrial scale inenvironmentally friendly conditions. Presents the fundamentals of photoelectrocatalysis Outlines photoelectrocatalytic green chemistry Reviews photoelectrocatalytic remediation of harmful compounds, hydrogen production, and CO2 reduction Includes photocorrosion, photoelectrocatalytic reactors, and modeling along with kinetic aspects

There has been a resurgence of interest in light-induced water splitting as the search for storable carbon neutral energy becomes more urgent. Although the history of the basic idea dates back more than four decades, efficient, economical and stable integrated devices have yet to be realized. In the continuing quest for such devices, the field of photoelectrochemistry is entering a new phase where the extraordinary interdisciplinary of the research and development efforts are opening new avenues. This aspect of current research effort is reflected in the chapters of this book, which encompass present thinking in the various disciplines such as materials science, photo-electrochemistry and interfaces that can contribute to realization of viable solar fuel generators. This book presents a blend of the background science and recent advances in the field of photoelectrochemical water splitting, and includes aspects that point towards medium to long term future realization. The content of the book goes beyond the more traditional approaches to the subject by including topics such as novel excitation energy processes that have only been realized so far in advanced photonics. The comprehensive overview of current activities and development horizons provided by the impressive collection of internationally renowned authors therefore represents a unique reflection of current thinking regarding water splitting by light.

Electrodeposited porous Ni electrodes were fabricated to act as electrocatalysts in a photo water splitting reaction. The electrodes were made porous by incorporating various Zn, Mn, Co and NH4+ based precursors. A Watt's bath was used to make electrodes at 60 °C and at 45 mA/cm2. Enhanced co-deposition of precursor ions was done at 50 mA/cm2. The precursor ions were leached out in 6M KOH for 48 hours to create porosity in the electrode. These electrodes were tested for their current densities against a Pt mesh in both anodic and cathodic conditions. It was observed that electrodes had enhanced anodic and cathodic properties. Some of the precursors favoured the OER and some favoured the HER. The electrode prepared using NH4Cl precursor gave anodic current densities up to 125 mA/cm2 and the electrodes prepared by (NH4)2SO4 generated cathodic current densities up to 200 mA/cm2. Long term stability test were done for 400 hours at 1.8 V and generated current densities of 12.5 mA/cm2. Once the performance of the electrodes was determined 1' x 1' electrodes were prepared. These electrodes were used as anode and cathode respectively in a substrate-type photoelectrochemical (PEC) cell used to produce hydrogen and oxygen from 6M KOH. The voltage required to split the water molecule in the electrolyte is generated by a 12" x 11" triple junction a-Si solar cell. The PEC cell gave an efficiency of 2.3 % under a tungsten filament lamp with an intefrated flux of 1000 Wm2.
