| Abstract | The present study demonstrates the catalytic reduction of PNP to PAP by N2H4 in the presence of our room temperature synthesized Ni–Pd bimetallic nanoparticles (BMNPs) in aqueous alkaline solution. NixPd100−x BMNPs of different compositions were synthesized by co-reduction of hydroxides of Pd2+ and Ni2+ in the presence of PVP at 298 K. The bimetallic structure of the NixPd100−x nanoparticles is confirmed by XRD, TEM, TEM-EDS, HRTEM, SAED and XPS studies. Among the various compositions Ni70Pd30 shows maximum efficiency towards the catalytic reduction of PNP to PAP in the presence of hydrous hydrazine. Detailed kinetics analysis at room temperature revealed that the reduction follows the Langmuir–Hinshelwood mechanism where PNP reduction occurred through intermolecular electron transfer between N2H4 and PNP when both were adsorbed on the catalytic site. The catalyst remains active at the end of the reaction and can be recycled. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
