SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Journal of Catalysis is the premier scholarly publication in the field of catalysis and an indispensable source of information for chemists and chemical engineers in both industrial and academic fields. Over the last decade, Journal of Catalysis has been ranked among the top five chemical engineering journals in terms of impact and relevance. During this period, it has published some of the most important contributions to physical chemistry and the science and applications of catalysis.
Journal of Catalysis publishes original, rigorous, and scholarly contributions in the fields of heterogeneous catalysis and homogeneous catalysis. These include studies that relate catalytic function to fundamental chemical processes at surfaces and in metal complexes, novel concepts in surface chemistry, the synthesis and catalytic function of novel inorganic solids and complexes, spectroscopic methods for structural characterization, and theoretical methods of direct interest and impact in the science and applications of catalysts and catalytic processes.
Journal of Catalysis publishes manuscripts of archival value because of their significant fundamental and conceptual contributions to our understanding and practice of catalytic chemistries. The journal features authoritative articles, priority communications, research notes, and letters to the Editors.
Journal of Catalysis also publishes Priority Communications and Research Notes. Priority Communications contain unique, exciting, and novel results that provide compelling evidence for rapid publication; while results in such communications may be of a preliminary nature, experimental details must be fully documented and the results reliably reproduced. Research Notes typically contain data and concepts that resolve in a concise but rigorous manner issues raised in previous publications.
