A number of transition metal complexes have been investigated as potential electrocatalystsfor C02 reduction. Among these are rhenium monometallic complexes, which have shownunique activity towards C02 reduction. Further development of multimetallic systems,capable of storing multiple equivalents of electrons has shown some potential in increasingthe selectivity of the C02 conversion processes toward highly reduced products. This studyreports the synthesis and characterization of novel polynuclear rhenium(I) complexes whererhenium is incorporated to the bridging ligand tppq (2,3,7,8-tetra-2-pyridylpyrazino[2,3-g]quinoxaline), which is capable of attaching up to four metal centers. The resultingcomplexes were characterized using different spectroscopic techniques (infrared, UV-Vis,emission) and cyclic voltammetry. The results suggest that the synthetic procedure adoptedwas successful.

With the aim of identifying competencies specific to a Filipino chemistry teacher, the present study surveyed and interviewed chemistry education academics and pre-service chemistry teachers across the Philippines. The results are divided into two: the primary competencies and the secondary competencies. The primary competency got the highest rating in the survey while the secondary competency got the second highest as agreed upon by the academics and the pre-service teachers. Results of aspect 1 show the importance of pedagogical content knowledge. In aspect 2, however, good knowledge on assessment of a teacher is deemed necessary. Aspect 3 deals with the ability of the teacher to vary his/her teaching strategy while aspect 4 recommends teachers to invest on professional development.
